Was Jake's average running speed for the first hour of his 26-mile marathon 11 miles per hour?

(1) He ran the entire 26 miles in 2.5 hours

(2) He ran the last 15 miles in 1.5 hours

OA later.

C

Will you explain pls?

i think i am missing something here but here is why I answered C:

total distance = 26

total time = 2.5 hours

last 15 miles took 1.5 hours, remaining (26-15) 11 miles must have taken (2.5-1.5) = 1 hour.

I am little confused. let me know if any.
