Jen ran for 10 minutes with the speed of 6 mph and then walked for 30 minutes at a speed of 3 miles per hour. What is the total distance covered by Jen?

The total distance covered by Jen was 4 miles.

Step-by-step explanation:

The formula for the average speed is shown below:

speed = distance / time

In this question we need to find the distance covered, therefore we will adjust the formula as shown below:

distance = time*speed

We will need to convert the time from minutes to hours, we do that by dividing by 60.

The total distance covered by Jen is the sum of the distances on each stage of his course, therefore:

total distance = distance 1 + distance 2

Applying the correct formula:

total distance = (time1 * speed1) + (time2 * speed2)

total distance = [ (10/60) * 6] + [ (30/60) * 3]

total distance = [60/60] + [90/60] = 1 + 3 = 4 miles

THe total distance covered by Jen was 4 miles.
