Question

A cyclist travels 27 km in 3 hours, whereas a car covers 70 km in 2 hours. find the ratio of their speeds.​

Answer 1

cyclist= 27/3=9:1

car=70/2=35:1

Answer 2

$Ratio=9:35$Concept:

We use Speed-distance relation.

Given

A cyclist travels 27 km in 3 hours, whereas a car covers 70 km in 2 hours.

Find:

The ratio of speeds

Solution:

We  know

$speed=\frac{Distance}{time}$

For cyclist

$S_{1}=\frac{27km}{3hours}\\S_{1}=9kmph$

For Car

$s_{2}=\frac{70km}{2hours} \\s_2=35kmph$

Hence the ratio is

$Ratio=9:35$
