Distance =240km

Time taken =4 hours

Speed= Distance covered /time taken =240km/4 hr

                        =60km/h

Speed of train =60km/h.

Answer 2

Given: The distance between two places is $484$km, and a train can cover that distance in $7$hours $20$minutes.

We have to find the speed of the train.

As we know that$\text { Speed }=\frac{\text { Distance }}{\text { Time }}$.

By using this formula, $\text { Speed }=\frac{\text { Distance }}{\text { Time }}$we are finding the speed of the train.

We have,

Distance$=484 \mathrm{~km}.$

Time$=7 \text { hours } 20 \mathrm{~min}.$

Now,

$\begin{array}{l}\text { Speed }=\frac{\text { Distance }}{\text { Time }} \\\\=>\text { Speed }=\frac{484}{7+\frac{20}{60}} \\\\=>\text { Speed }=\frac{484}{7.33} \\\\=>\text { Speed }=66\end{array}$

We get, $\text { Speed }=66 \mathrm{~km} / \mathrm{hr}$

Hence, the speed of the train will be$66 \mathrm{~km} / \mathrm{hr}$.
