s=a+(a+10)+(a+10+10)+(a+10+10+10)
s=4a+60
a=(s-60)/4
24kmph
time taken = x/40 + 2x/20
=> x=8
so, 3x = 24
9/32
444km
Since the speed diff is 5km/h
It takes 12 hrs to cover 60 extra kms
Therefore in 12 hrs the total dist covered is
Relative speed×time=(21+16)×12=444 kms
50 each
3x -y = 100
4x-2y = 100
3 minutes
these r all factors of 30
1*30=30
2*15=30
3*10=30
5*6=30
like that
B

3×8=24=2xt ===> t=12hours
