Question

A 200m long train crosses another train in opposite direction in 15sec . if the length of the another train is 300m &speeds of both the trains are equal find speed of train?(tip. give me solution also)​

Answer 1

$\frac{100}{3} {ms}^{ - 1}$

Step-by-step explanation:

it crosses a distance of 500m in 15 secs

speed of train is x, relative speed 2x

$2x = 2 \times \frac{500}{15}$

$2x = \frac{200}{3} {ms}^{ - 1}$

$x = \frac{100}{3} {ms}^{ - 1}$
