When you catch up, the distance traveled is the same
Distance = rate x time
r = uncle's rate
30 min = 30/60 hr = uncle's time
25 min = 25/60 hr = your time
Uncle's distance = Your distance
(r)(30/60) = (r + 10)(25/60)
(r)(1/2) = (r + 10)(5/12)
r/2 = 5r/12 + 50/12
6r = 5r + 50
r = 50
Uncle's rate = 50 mph
Your rate = 50 + 10 = 60 mph
