Question

किसी रेलगाड़ी की बिना रुके गति 60 km/h है और रुकने पर 40 km/h है, तो वह 1 घंटा में कितना मिनट रुकेगी?​

Answer 1

Given:

किसी रेलगाड़ी की बिना रुके गति 60 km/h है और रुकने पर 40 km/h है,

To find:

तो वह 1 घंटा में कितना मिनट रुकेगी?​

Solution:

The average speed of the train without stoppage = 60 km/hr

The average speed of the train with stoppage = 40 km/hr

∴ The difference in the average speed of the train = 60 - 40 = 20 km/hr

We know,

$\boxed{\bold{Stop \:time = \frac{Difference \:in \:Average\:speeds}{Speed\: without \:stoppage} \times 60 }}$

Therefore,

The time of rest per hour will be,

= $\frac{20}{60} \times 60$

= $\bold{20\:minutes}$

Thus, the train stops for 20 minutes in 1 hour.
