Question

7. A motorbike covers a certain distance at a uniform speed of 66 2/3 km per hour. How much

distance will it cover in 9 hours?​

Answer 1

Distance covered by the motorbike = s

Speed by which it is travelling, $v = 66\dfrac{2}{3} \; km/h = \dfrac{200}{3} \; km/h$

Time taken by the cover this distance, $t = 9 \; h$

• $v = \dfrac{s}{t}$

• $\dfrac{200}{3} = \dfrac{s}{9}$

• $s = \dfrac{200\times9}{3}$

• $s = 600 \; km$

Therefore, the distance covered by the motorbike is 600 km.
