Time Distance and Speed
Two trains are traveling from point A to point B such that the speed of first train is 65 kmps and the speed of 2 train is 29 kmph. Where is the distance b/w A&B such that the slower train reached 5 hrs late compared to the faster?

-
- if x is the distance, then
x/29 - x/65 = 5
Then x = 5*65*29/(65-29) = 5*65*29/36 = 261.8055 kms - 13 years agoHelpfull: Yes(34) No(2)
- please see 65 kmps
and 29 kmph - 13 years agoHelpfull: Yes(7) No(3)
- DIPIN and his method, both are right. Its 261.8055 kms from A

- suppose distance is x km.and time taken by faster abd slower trains are t1 and t2 respectivly.
t2-t1=5;
(x/29)-(x/65)=36x/29*65
5=36x/29*65
x=261.805. - 13 years agoHelpfull: Yes(5) No(0)
- 65-29=36*5=180

- for every 1 hr the second train is late by 36kms from the first train.so why can't the answer be 36*5=180kms

- Distance is same for both trains so
let distance = D
speed of first train s1 = 65kmph
speed of second train s1 = 29kmph
(D/s1)-(D/s2) = t1 - t2
(D/65)-(D/29) = 5
just solve the equation - 8 years agoHelpfull: Yes(0) No(0)
- use this formula
time=distance/velocity
given, v1-v2=5, d1=d2
put the data and get the result
Ans is(261.805) - 8 years agoHelpfull: Yes(0) No(0)
