Question

A bus travels 120 km in 3 hours, while a car travels 400 km in 5 hours. Find the ratio of the speed of the bus to that of the car.
$(speed=\frac{distance}{time})$

• A. 2:1
• B. 1:4
• C. 2:3
• D. 1:2

Answer 1

The correct option is D 1:2

We know that speed = $\frac{distance}{time}$

Speed of the bus = $\frac{120}{3}$ = 40 km/hr

Speed of the car = $\frac{400}{5}$ = 80 km/hr

Hence, the ratio of the speed of the bus to that of the car = $\frac{40}{80}$ = $\frac{1}{2}$ = 1:2
