Question

Jack is running 2.45 miles ahead of Rashad. Jack runs at a pace of 5.5 miles per hour. Rashad runs at a pace of 7.75 miles per hour. Let x represent the number of hours since Rashad started running.

Answer 1

Runner A will be 72 × 10³ m away from the starting point at time t = 45 s, and Runner B will be 64 m away from the starting point at time t = 45 s.

Step-by-step explanation:

In this problem, we need to find the distance from the starting point that each runner will be at time t = 45 s. We are given that both runners reach a distance of 64 m from the starting point at time t = 25 s. To find the distance at time t = 45 s, we need to calculate how far each runner would have traveled in the 20 seconds between t = 25 s and t = 45 s.

Since both runners continue at the same speeds, Runner A will have been running for 20 seconds longer than Runner B. Therefore, Runner A will be 72 × 10³ m away from the starting point at time t = 45 s, and Runner B will be 64 m away from the starting point at time t = 45 s.
