Josh runs 7 miles in 36 minutes. Keria runs 3 miles in 15 minutes Which runner is faster
36 / 7 = ________ minutes per mile
15 / 3 = ________ minutes per mile
To determine which runner is faster, we can compare their average speeds. The average speed of a runner can be calculated by dividing the distance covered by the time taken.
Let's start by calculating the average speed of Josh:
Distance covered by Josh = 7 miles
Time taken by Josh = 36 minutes
Average speed of Josh = Distance / Time = 7 miles / 36 minutes = 0.194 miles per minute
Now, let's calculate the average speed of Keira:
Distance covered by Keira = 3 miles
Time taken by Keira = 15 minutes
Average speed of Keira = Distance / Time = 3 miles / 15 minutes = 0.2 miles per minute
Comparing their average speeds, we can conclude that Keira is faster. Keira's average speed is 0.2 miles per minute, which is higher than Josh's average speed of 0.194 miles per minute.
