Question

A bus takes 8 hours to cover a distance of 320 km. What is the average speed of the bus?

Answer 1

time = 8 hours
distance = 320 km

average speed = total distance covered/ total time taken

= 320/8
= 40

so, the average speed of the bus is 40km/h

Answer 2

"The average speed of the bus is $40\quad { km }/{ h }$

Solution:

Given,

Time taken by a bus to cover 320Km is 8 hours

Here, d = 320 Km and T = 8hours

We know that,

$Average\quad speed\quad =\quad \frac { Total\quad distance\quad covered }{ Total\quad timetaken }$

$=\quad \frac { 320 }{ 8 }$

$=\quad 40\quad { Km }/{ hr }$

The average speed can be defined as the ratio between the total distance covered to the total time taken."
