4th grade math the blue shark can swim at a speed of 40 miles per hour. If the shark swam at this speed for 15 min. How far would it swim?
---------------
15 minutes is 1/4 of an hour
----
In 1/4 of an hour the shark could swim (1/4)*40 mph = 10 miles
------------------------------
How long would it take the shark to travel 90 miles?
------------
distance divided by rate = time
---
time to travel 90 miles at 40 mph = 90/40 = 9/4 = 2 1/4 hrs = 2 hrs and 15 min
