Question

If a bus travels $240km$ in $4hours$ and a car travels $375km$in $5hours$at a uniform speeds, then the ratio of the distances travelled by them in one hour is

• A. $1:2$
• B. $8:5$
• C. $5:6$
• D. $4:5$

Answer 1

The correct option is D

$4:5$

The distance covered by the bus in $4h=240km$

So, the distance covered by the bus in $1h=\frac{240}{4}=60km$

The distance covered by the can in $5h=375km$

So, the distance covered by the car in $1h=\frac{375}{5}=75km$

Ratio $=$Distance covered by the bus : Distance covered by the car

$$\begin{gathered} =60:75 \\ =4:5 \end{gathered}$$

Hence, the required ratio is $4:5$

So, the correct option is D.
