Question

How long a train will take to travel a distance of
$200km$ with a speed of $60km{h}^{-1}$ .

Answer 1

Distance covered by train (𝑑) = 200 𝑘𝑚
And speed of train $=60km{h}^{-1}$
Using formula of speed,
$\text{Speed}=\frac{\text{Distance travelled (d)}}{\text{Time taken}}$
$60km{h}^{-1}=\frac{200km}{\text{Time taken}}$

$\text{Time taken}=\frac{200}{60}=\frac{10}{3}h$
$=3\frac{1}{3}h=3h+\frac{1}{3}\times 60min$
$=3\text{hour}20\text{minutes}$

𝐻𝑒𝑛𝑐𝑒, time taken = 3 hour 20 minutes
