Time Distance and Speed
A train can travel 50% faster than car.Both start from point A and reach point B 75km away from A at the same time.on the way,however,the train lost about 12.5 minutes while shopping at the stations.the speed of car is....?????
Read Solution (Total 3)
-
- Let speed of the car be x kmph
speed of the train is (150/100)*x = 3/2*x kmph
so,
75/x - 75/(3/2)*x = 125/(10*60)
solving we get
x = 120 kmph
so speed of the car is 120 kmph - 9 years agoHelpfull: Yes(7) No(1)
- velocity of car=v, velocity of train=1.5v,
1.5vt=v(t+12.5/60)
t=10/24 hr
t for car=10/24 + 12.5/60
=15/24
velocity of car=75/15/24=120km/hr - 9 years agoHelpfull: Yes(2) No(1)
- 120 kmph.and train velocity 180kmph
- 9 years agoHelpfull: Yes(1) No(1)
