Time Distance and Speed
a train travels 50%faster than a car.both start from point a A at the same time and reaches point B 75 km away from A at the same time.on the way the train lost about 12.5 min due to stoppages.the speed of the car?
Read Solution (Total 11)
-
- speed of car=x
speed of train=3x/2
75/x-75/3x/2=12.5/60
solving above equation we get x=120
speed of car=120km/h
speed of train=180km/h. - 10 years agoHelpfull: Yes(50) No(0)
- let speed of car=x
so speed of train=x+x/2=3x/2
75/x=75*2/3x +5/24
x=120km/h
so speed of car=120km/h - 10 years agoHelpfull: Yes(7) No(0)
120kmph

- let the time taken by car be t
the train wasted its 12.5 hrs in stopping
otherwise it would have taken 12.5/60 hrs less
let speed be x
then atq,
(x+ 0.5x) (t-(12.5/60))=75=xt
therefore on solving the eq. we will get,
x=120kmph - 10 years agoHelpfull: Yes(2) No(0)
- take,speed of car=x
then speed of train=3x/2
75/x-75/3x/2=12.5/60
solving above equation we get x=120
speed of car=120km/h
speed of train=180km/h. - 10 years agoHelpfull: Yes(1) No(0)
- let speed of car=x then speed of train=3x/2
then
75/x=75/(3x/2)+12.5
=>x=2 - 10 years agoHelpfull: Yes(1) No(1)
- speed of car=x
speed of train=x+x/2=3x/2
now
75/x-75/(3x/2)=12.5/60
on solving
x=120km/hr
speed of train=180km/hr - 10 years agoHelpfull: Yes(1) No(0)
- 120kmph speed of car
- 10 years agoHelpfull: Yes(0) No(0)
- speed of car=x
speed of train=(x+50x/100)=3x/2
t=d/s
12.5/60=75/x-75/3x/2
x=120
speed of car=120km/h - 10 years agoHelpfull: Yes(0) No(0)
- speed of the car=120km/hr
- 10 years agoHelpfull: Yes(0) No(0)
- 120kmph is the speed of car
- 10 years agoHelpfull: Yes(0) No(0)
