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

Answer:

answer is attached above!!!!

Answer 2

Concept: The speed of the cyclist and car will be the distance covered by them in particular time period.

Given: Distance covered by cyclist = $27$ $km$

and time taken by cyclist = $3$ $hr$

Distance covered by car = $70$ $km$

and time taken by car= $2$ $hr$

Find: Ratio of the speed of the cycle and speed of the car

Solution:

Speed of the cycle = $\frac{Distance\ covered}{time\ taken}$

Speed of the cycle = $\frac{27\ km}{3\ hr} = 9\ kmph$

Speed of the car = $\frac{70\ km}{2\ hr} = 35\ kmph$

Therefore,

Ratio of the speed of the cyclist to the speed of the car = $9:35$
