Avinash covered 150 km distance in 10 hours. The first part of his journey he covered by car, then he hired a rckshaw. The speed of car and rickshaw is 20km/hr and 10km/hr respectively. The ratio of distances covered by car and the rickshaw respectively are :

Options

A. 2:3
B. 4:5
C. 1:1
D. none of these

Answer

C

Explanation

The average speed of Avinash
= (150)/(10) = 15km/hr

It means the rickshaw took 5/8 and car took 3/8 of the total time i.e., the ratio of time taken by rickshaw to car is 5:3.
So the ratio of distances covered by rickshaw to car is
`5xx12:3xx20 implies 1:1`
