Question

Joshua wants to complete the first mile of a 5-mile run in 10 minutes or less running at a steady pace. The inequality 5 - p 6 ≤ 4 can be used to find p, the pace, in miles per hour, he can run to reach his goal. Solve the inequality.

Answer 1

The given inequality is
5 - p⁶ ≤ 4
Solving the inequality to find for the possible values of p
-p⁶ ≤ 4 - 5
-p⁶ ≤ -9
p⁶ ≥ 9
p ≥ 1.44
The speed of Joshua is at least 1.44 miles per hour
