Question

If a car travels 287 miles in 3 hours and 30 minutes what is the average miles per hour that they traveled

Answer 1

It's simple just divide the total Miles traveled by the total hours;

287 m ÷ 3.5 (it's 3.5 because 30 mins is half of an hour) 

$\frac{287 miles}{3.5 hours}$ = 82 miles per hour 

So your final answer would be 82 miles per hour  :)
