Question 837439



a manatee can swim 5 miles in 1 1/4 hour. if the manatee swims at the same average speed, how far can it swim in 1 hour ? 

---------------------------------------------------------
1st) Set up a proportion. Make sure that both ratios/fractions have the same things on top and bottom. If you put miles on the top of one, the other has to have miles on the top as well. **Note: 1/4=0.25


(5 miles)/(1.25hours)=(x miles)/(1 hour))


--------------------------------------------

2nd) Cross multiply.

1.25x=5
1.25x/1.25=5/1.25
x=4


--------------------------------------------
The manatee can swim 4 miles in 1 hour.
