Question

if a train runs at 45km/hr how far does it go in 8 sec

Answer 1

Hey dear friend

Given-:
Speed of a train=45km/h
Time taken=8sec

To Find-:
Distance=?

By the formula
Speed=Distance/Time taken
45km/h=Distance/8sec

Changing km/h into m/s
45000m/3600sec=Distance/sec
Distance=12.5*8
Distance=100m

So, the train goes 100m/0.1km far in 8sec.

Answer 2

hello here is your answer
the speed is 45km/hr so it's 45×5/18= 225/18
therfore distance= speed× time
= 225/18×8
= 12.5×8
= 100m.


hope it helps!
