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
