Accepted Solution
A:
I added a screenshot with the complete question
Answer: Total miles = 2.5 miles
Explanation: 1- While walking: We are given that Joelle walked 20 minutes at a rate of 3 miles per hour. This means that she walked [tex] \frac{20}{60} = \frac{1}{3} [/tex] of an hour at a rate of 3 miles per hour The formula that relates distance, time and velocity is: Distance = velocity * time Substitute with the givens to get the distance she covered while walking: Distance = 3 * [tex] \frac{1}{3} [/tex] = 1 mile
2- While running: We are given that Joelle ran 15 minutes at a rate of 6 miles per hour This means that she ran [tex] \frac{15}{60} = \frac{1}{4} [/tex] of an hour at a rate of 6 miles per hour The formula that relates distance, time and velocity is: Distance = velocity * time Substitute with the givens to get the distance she covered while running: Distance = 6 * [tex] \frac{1}{4} [/tex] = 1.5 miles
3- getting the total mileage: Total distance she covered = distance while walking + distance while running Total distance she covered = 1 + 1.5 Total distance she covered = 2.5 miles
