What should be the speed of the train to cover the same distance in 3 hours?

SOLUTIOn

✰ A train moving at a speed of 75 km/hr covers a certain distance in 4.8 hours.

• Speed = 75 km/h
• Time = 4.8 hours
• Distance = ?

Appy formula

$\implies\tt Speed=\dfrac{Distance}{Time} \\ \\ \\ \implies\tt Distance=Speed\times{Time} \\ \\ \\ \implies\tt Distance=75\times{4.8} \\ \\ \\ \implies\tt Distance= 360km$

__________________________

✰ The speed of the train to cover the same distance in 3 hours

• Time = 3 hours
• Distance = 360 km
• Speed = ?

$\implies\tt Speed=\dfrac{Distance}{Time} \\ \\ \\ \implies\tt Speed=\dfrac{360}{3} \\ \\ \\ \implies\tt Speed=120km/h$

Hence, Speed of the train to cover the 360km distance in 3hour is 120km/h
