Answer:
8:04 am
Step-by-step explanation:
The first train travels 60 miles from 6am to 7am
So at 7am the trains are 455 - 60 = 395 miles apart
First train: Distance from town A (DA) = Velocity* time = 60t
Second train: Distance from town B (DB) = Velocity*time = 70t
So, DA + DB = 60t + 70t
395 = 130t
t = 395/130
= 3.4 hrs
= 3 hrs 4 mins
The first train left at 5am so the exact time would be 8:04am (5am +3 hrs and 4 minutes)
(1, 64), (2, 32), (4, 16), (8, 8).
