Question

A cab has an average speed of 60 km/hr whilegoing from indore to ujjain and has an average speed of x km/hr while returning the same distance from ujjain to indore if the average speed of the cab for the whole journey is 48 km/hr find the value of x

Answer 1

While returning from Ujjain to Indore the speed of cab was 36 km/hr

Step-by-step explanation:

A cab has an average speed while going from Indore to Ujjain = 60 km/hr

The average speed of the cab for the whole journey = 48 km/hr

While returning from Ujjain to Indore the average speed = x km/hr

$Average=\frac{\text{sum of the terms}}{\text{number of terms}}$

$48=\frac{x+60}{2}$   [multiply both side by 2]

96 = x + 60  

x + 60 = 96     [subtract 60 from both side]

x + 60 - 60 = 96 - 60

x = 36

While returning from Ujjain to Indore the speed of cab was 36 km/hr
