A plane flew at a constant speed and traveled 762 miles in 5 hours how many miles would the plane travel in 3 hours at the same speed
Consider that the plane traveled 762 miles in 5 hours. If I write that as a fraction it is 762mi/5hours. I can make this a unit rate by saying762/5=762÷5=152.4. This means 762mi/5hours is the same as 152.4mi/1hour. So the plane travels 152.4 miles every one hour.
152.4 x 3 is therefore how far the plane travels in 3 hours. 152.4*3=457.2
So the plane travels 457.2 miles in 3 hours.
