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

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)

37. 50

38. 50.4

39. 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

40. 50.4km/hr

41. 50.4 km/hr

42. 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

43. 50.4 km/hr

44. B) 50.4 km/hr

45. 50.4 km/hr

46. 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

47. 70km/hr

48. 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

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

50. B

51. 50.4km/h

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

53. 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

55. 50.4 KM/HOUR

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

57. 50.4

58. B

59. 50.4 km/hrs

60. 14 × (3600÷1000) = 50.4

61. 50.4 Km/Hr

62. 1Hr = 3600s
14*3600= 50400m/hr
50.4 *10^3m/hr = 50.4 km/hr

63. 50.4 km/hr

64. 50.4 km/hr

65. 50.4 km/hr

66. b

67. 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

79. 70

80. 50.4km/h

81. 50.4km/hr

82. 1m/s = 18/5 km/he
So, 14m/s= 14*18/5
= 50.4 km/hr

83. Just multiply the value by 3.6

14m/s * 3.6 = 50.4 km/hr

94. 50.4 km/hr

95. 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

96. 1m/s=3.6km/h
Therefore 14m/s=14*3.6=50.4km/h

100. 50.4 km/hr

101. 50.4kh/hr

102. 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

103. 50.4 km/hr

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

105. 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

106. 50.4km/hr

107. C

108. C

109. the substitution is as follows

110. 28km/hr

111. 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

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