Answer 2

Answer:

Time = 5 hours

Step-by-step explanation:

Given that-

A train takes 3 hours to reach a station B from station A.

Distance between A and B = 144 km

Time = 3 hours

Speed = ?

Using formula-

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

                  = $\dfrac{144}{3}$

Speed = 48 km/hour

Again,

Distance = 240 km

Time taken by train to cover distance = ?

Using formula-

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

               = $\dfrac{240}{48}$

Time = 5 hours
