Mathew Brown · Answer 1

49 1/8 minutes

Step-by-step explanation:

Jamie has 1/4 of the 26.2 mile distance to go, so must finish ...

(26.2 mi) / 4 = 6.55 mi

The time in hours required to do that is found by dividing distance by speed:

time = distance/speed = (6.55 mi) / (8 mi/h) = 0.81875 h

In minutes, this is ...

(0.81875 h) * (60 min/h) = 49.125 min = 49 1/8 min

It will take Jamie 49 1/8 minutes to finish the race at her current speed.
