Question

A car travels 165 km in 3 hours.

(i) How long will it take to travel 440 km?
(ii) How far will it travel in 7 hours?

Answer 1

A car travels 165 km in 3 hours.

$\therefore$ Speed of the car = $\frac{\mathrm{Distance}}{\mathrm{Time}}=\frac{165}{3}=55\mathrm{km}/\mathrm{h}$

(i) Time taken by the car to travel 440 km = $\frac{440}{55}=8\mathrm{hours}$

(ii) Distance travel by the car in 7 hours = $55\times 7=385\mathrm{km}$
