1. B

2. 50.4 km / hr

3. Option B is correct

4. (1*18/5) = 3.6kmph
1mps = 3.6kmph
14mps * 3.6kmph = 50.4kmph

5. B

6. 1 m/s = 3.6 km/hr
14 m/s x 3.6 = 50.4 Km/hr

Option B is Correct

7. 1 m/s = 3.6 km/hr
14 m/s x 3.6 = 50.4 Km/hr

Option B is Correct

10. 1 SEC 14 MTR
1 MINURE 840 METER
1 HOUR IS 840 *60 = 50.400MTR

11. 70km

12. 50.4

13. B

14. 50.4 km/hr

15. 50.4 km/hr

16. 1 sec = 1/3600 hr
1 meters = 1/1000
So,
(14/1000)÷(1/3600)= 50.4 km/hr

17. 1 second = 14 meters
1 minutes = 14×60 (1 min = 60sec)
= 840 meters
1 hour = 840 ×60
= 50400 meters (1hour = 60 minutes)
50.4 km/h

18. B

19. 50.4 km/hr

20. 14m/s * 60seconds*60 minutes / 1000= 50.4km/hr

36. 50

37. 50.4

38. Given speed = 14 m/s
To change m/s to km/hr we can multiply the speed with 18/5
14*(18/5) = 50.4 km/hr

As we know
1km = 1000 m
And 1hr = 3600 sec
So 1km/hr = 1000/3600 m/s
= 5/18 m/s

39. 50.4km/hr

40. 50.4 km/hr

41. 14 metres/second is your query

by logical deduction, 1 metre per second equals 3600 metres/HOUR

move the decimal over to the left 3 places (thousandths) ↩️↩️↩️

This gives you 3.6

Now multiply 3.6×14 = 50.4

Good mathematical exercise

42. 50.4 km/hr

43. B) 50.4 km/hr

44. 50.4 km/hr

45. 50.4km/hr
14 meter/s
1min =60second
1000meter = 1 km
14*60= 840meter in one mint
60min = 1 hour
So, 840*60 =50400meter
50400/1000 = 50.4km/h

• 50.4km/hr

46. 70km/hr

47. 50.4 km/hr (explainantion : 1 min = 60 sec & 60 min= 1 hr 14 * 60 sec= 840 meters & 840*60 min = 50400 meters , now 1 km = 1000 m ,so 50400/1000 = 50.4 km/hr

48. B) 50.4km/hr
1km=1000m
50.4km=50400m
then lets convert given hr into sec
50400/60=840
840/60=14m/s

49. B

50. 50.4km/h

51. Given 14 meeter /sec
So per minute=840 meeter
per hour=50400 meeter
1 km=1000meeter
So ans is 50.4km/hr

52. 50.4

convert 14 meters in to KM —- 14/1000=0.014 Km
Convert seconds into hrs —– 1*60*60 = 3600

0.014 km per —— 1 sec
? ——- 3600

cross multiple 3600*0.014/1= 50.4 Km/hr

54. 50.4 KM/HOUR

55. Speed=14m/s=14*(18/5)kmph=50.4kmph

56. 50.4

57. B

58. 50.4 km/hrs

59. 14 × (3600÷1000) = 50.4

60. 50.4 Km/Hr

61. 1Hr = 3600s
14*3600= 50400m/hr
50.4 *10^3m/hr = 50.4 km/hr

62. 50.4 km/hr

63. 50.4 km/hr

64. 50.4 km/hr

65. b

66. given speed = 14m/s
so,,,,for 1min=14*60=840m
then..for 1hr= 840*60=50400m
we all know 1000m=1km
so…50400m = 50.4km/hr

• we all know m/s convert into km/hr 18/5
So direct we can solve 14 × 18/5
it’s 50.4 km/hr

73. 14 *60m. = 60 sec
840 m.= 60 sec
840*60m = 60*60 sec
50400 m = 36000 sec
50400m = 1 hr.
50400/1000
ans= 50.4 km/hr

78. 70

79. 50.4km/h

80. 50.4km/hr

81. 1m/s = 18/5 km/he
So, 14m/s= 14*18/5
= 50.4 km/hr

82. Just multiply the value by 3.6

14m/s * 3.6 = 50.4 km/hr

83. 70km/hr

92. 50.4 km/hr

93. 14 m/s
1hr=3600 sec
so multiply by 3600 and dvide by same
14*3600/3600 m/s
50400/3600 m/s
3600 s = 1hr
1000m=1km
50400=50.4km
so
50.4km/hr

94. 1m/s=3.6km/h
Therefore 14m/s=14*3.6=50.4km/h

98. 50.4 km/hr

99. 50.4kh/hr

100. 3,600 seconds = 1 minute
1Km = 1000m
Therefore 3,600/1000 = 3.6 m/s
Final answer = 14 metres * 3.6 = 50.4km/hr

• 1hour=3600seconds

101. 50.4 km/hr

102. Basically to get all you need to do is
14×3.6= 50.4

103. convert 14 meters in to KM —- 14/1000=0.014 Km
Convert seconds into hrs —– 1*60*60 = 3600

0.014 km per —— 1 sec
? ——- 3600

cross multiple 3600*0.014/1= 50.4 Km/hr

104. 50.4km/hr

105. C

106. C

107. the substitution is as follows

108. 28km/hr

109. Therefore, 1km = 1000 meters
⇒1 meter = 1 km1000
Definition of Hour: A period of time equal to 60 minutes that is 3600 seconds.
Definition of second: It is measured as the smallest unit of time.
⇒1 second =1 hr3600
Now, 14meters per second need to be converted to kilometers per hour.
Let x be 14 meters per second which is needed to convert into kilometers per hour
⇒x = 14ms
⇒141 km10001 hr3600
⇒14×36001000kmhr=50.4kmhr
Therefore, 14 meters per second is equal to 50.4 kilometers per hour

110. b) 50.4km/hr
1km=1000m
50.4km=50400m
then lets convert given hr into sec
50400/60=840
840/60=14m/s
