Question

A train moving with uniform speed covers a distance of $120\mathrm{m}$ in$2\mathrm{s}$. Calculate: the time it will take to cover $240m$

Answer 1

Step 1 Given,

1. Distance covered = $120\mathrm{m}$
2. Time taken = $2\mathrm{s}$

Step 2 Formula Used,

1. Speed = ${\displaystyle \frac{\mathrm{distance}}{\mathrm{time}}}$

2. Time taken to cover $240m$ is,

$Time=\frac{dis\tan ce}{speed}$

Step 3 Solution,

$$\begin{gathered} Speed=\frac{120}{2} \\ =60\mathrm{m}/\mathrm{s} \end{gathered}$$

$$\begin{gathered} Time=\frac{240}{60} \\ =4s \end{gathered}$$

Time taken to cover $240m$ is $4s$
