. Math and Science A gray whale traveled 152 kilometers in one day. The whale
swam between 7 and 8 kilometers each
hour. About how many hours did it take
the whale to swim the distance? Show
two different ways that you can use
compatible numbers to find an answer.
Then solve.

20.25 hours

Step-by-step explanation:

t=d/v

t=152/7.5

t=20.25 hours

7.5km/hr=152km/x

152/7.5=20.25

20.25*1=20.25=x
