Question

Harvey the wonder hamster can run 3 1/6 km in 1/4 hour find his average speed in kilometers pe hour

Answer 1

Answer:- The average speed of Harvey the wonder hamster is
`12(2)/(3)\ km/hour`.

Explanation:-

Given: Distance traveled by Harvey
`=3(1)/(6)\ km=(19)/(6)\ km`

Time taken
`=(1)/(4)\ hour`

`Speed=(Distance)/(Time)\\\Rightarrow\ Speed=((19)/(6))/((1)/(4))\\\\=(19*4)/(6)\\\\=(38)/( 3)\\\\=12(2)/(3)\ km/hour`

Therefore, the average speed of Harvey the wonder hamster is
`12(2)/(3)\ km/hour`.

Answer 2

there are 4 quarters to 1 hour

3 1/6 x 4 =

19/6 * 4 = 76/6 = 12 4/6, reduces to 12 2/3 km per hour
