Question

A cyclist travel 40 km in 2 hours. What's the average speed?

Answer 1

Speed = distance/ time
Distance= 40 km
Time= 2hours
Speed= 40/2
= 20km/h

Answer 2

The average speed is 20 km/hr.

-------------------------------------------------------------------------------------

Let's understand a few concepts:

To solve the given problem we will use the following formula of average speed:

$\boxed{\bold{Average\:speed = \frac{Total \:Distance}{Total \:Time} }}$

---------------------------------------------------------------------------------------

Let's solve the given problem:

The total distance travelled by the cyclist = 40 km

The total time taken by the cyclist to cover 40 km = 2 hours

Therefore, by using the above formula, we get

The average speed of the cyclist will be,

=  $\frac{40\:km}{2\:hours}$

= $\frac{40}{2}\:km/hr$

= $\bold{20\:km/hr}$

Thus, the average speed of the cyclist is 20 km/hr.
