Answer:
- Wyatt: 1:27:16 HH:MM:SS
- Jackson: 1:31:18 HH:MM:SS
Step-by-step explanation:
We can use a proportion to find the running time in each case.
Wyatt
time/(10 mi) = (2/5 h)/(2 3/4 mi)
time = 10(2/5)/(2 3/4) h = 1 5/11 h ≈ 1 h 27 min 16 sec
__
Jackson
time/(10 m) = (4/3 h)/(8 2/3 mi)
time = (10)(4/3)/(8 2/3) = 1 7/13 h ≈ 1 h 32 min 18 sec
