Harvey the wonder hamster can run 3\dfrac16 \text{ km}3 6 1 km3, start fraction, 1, divided by, 6, end fraction, start text, space, k, m, end text in \dfrac14 4 1 start fraction, 1, divided by, 4, end fraction hour. Harvey runs at a constant rate.

Step-by-step explanation:

The calculation of average speed in kilometres per hour is shown below:-

As we know that

So, the average speed is

Now we will convert into a mixed number i.e

Now the cross cancel common factor is 2

So,

hence, the average speed is in kilometers per hour

Therefore we simply applied the above formulas to determine the average speed that comes in kilometers per hour
