Answer 2

Given :-

Two trains A and B of equal length of 200 m running in opposite direction  cross each other in 16 sec.

To Find :-

The speed of train 'A'.

Analysis :-

Using the formula of speed, find the speed by dividing distance by time.

Since the answer we get is in meter per second, convert it to kilometer per hour.

Solution :-

We know that,

• d = Distance
• t = Time
• s = Speed

By the formula,

$\underline{\boxed{\sf Speed=\dfrac{Distance}{Time} }}$

Given that,

Distance (d) = 200 m

Time (t) = 16 sec

Substituting their values,

$\sf Speed=\dfrac{200}{16}$

$\sf Speed=12.5 \ m/sec$

By converting,

Meter per second to kilometer per second = Meter per second × 18 ÷ 5

Substituting them,

$\sf =12.5 \times \dfrac{18}{5}$

$\sf =45 \ km/hr$

Therefore, the speed of train A is 45 km/hr.
