Answer:
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.
