Question

an airplane traveled 1536 miles in 3 hours. At this same rate, how far could the plane travel in 8 hours?

Answer 1

The plane can travel 4,096 miles in 8 hours.

Answer 2

8*(1536/3)
(Note that you could simply do 8/3 * 1536)
In order to find how many miles the plane can travel in 8 hours, you must first find the unit rate. In this case, we have to find how many miles the plane can travel in an hour.
In order to solve for the unit rate, we can simply divide 1536 by 3.
1536/3 = 512 miles / 1 hour
Now that we have the unit rate, we can multiply it by 8 in order to find our answer:
8 * 512 = 4096
The plane can travel 4096 miles in 8 hours.
Good luck!
