Aplane flew at a constant speed and traveled 762.5 miles in 5 hours
how many miles would the plane travel in 3 hours at the same speed?

We can solve this problem by the rule of three.

762.5 miles5 hours
x3 hours

x=(762.5 miles x 3 hours) / 5 hours=457.5 miles.

this plane would travel in 3 hours 457.5 miles.

Other method:
We can calculate the plane´s speed.
speed=distance /time.

speed=762.5 miles/5 hours=152.5 miles /hour

distance= speed x time
distance=(152.5 miles/hour)(3 hours)=457.5 miles.

this plane would travel in 3 hours 457.5 miles.
