Question

A train covers 51 km in 3 hours. Calculate its speed. How far does the train go in 30 minutes?

Answer 1

Given: A train covers 51 km in 3 hours,

Distance $=51km$
Time $=3hours$
Speed $=\frac{51km}{3hours}$ [$\because Speed=\frac{Distance}{Time}]$
$=\frac{17\times 3}{3}\frac{km}{h}$
$=17km/h$

Hence, the speed of the train is $17km/h$.
