Question

two trains each 225m long, moving in opposite directions, cross each other in 10 seconds. If one is moving twice as fast the other, find the speed of the Faster train.​

Answer 1

Answer:

Formula

$Speed = \frac{Distance}{Time}$

Since the fastest train is twice as fast as the other, we have to x2 the timetaken.

10 seconds x 2 = 20 seconds

$= \frac{225 metre}{20 seconds} \\\\= 11.25 m/s$

The speed for the fastest train is 11.25 m/s
