speed? How much faster? Show your work.

Answer 1

Answer:

Step-by-step explanation:\

A mako shark can swim 4 kilometers in 1/10 hour.

Speed = Distance/Time

= 4/(1/10)

= 40km/hour

A blue whale can swim 5 kilometers in 1/4 an hour.

This shows that the Mako shark is faster as it swims at rate of 40km/hour and the blue whale swims at 20km/hour. It's faster by 20km.

= 40km - 20km

= 20km
