Two people set off by car on a rally and take the same route which is 25 miles long. If A drives at an average speed of 50 miles per hour, and B at an average speed of 60 miles per hour, how much longer in minutes will it take A to cover the course than it takes B ?

Question

speed = distance / time

Solving for time, you get

speed * time = distance

time = distance / speed

Divide each distance by the speed to find the time.
Since the distance is in miles and the speed in mph, the time will come out in hours.
Then multiply each time by 60 to get minutes.
Then subtract the times in minutes to get your answer.
