Answer
It takes you 390 minutes to finish the race.
Work Step by Step
Let S = Total distance
V = Speed (mi/h)
t = Time
We have: 1 mile per hour = 0.44704 meters per second
Then at10 mi/h: $10 \times 0.44704=4.4704$ m/s
1 mile =1609.344 meters
For 65 mi: $65 \times 1 609.344=104607.36$ m
Substitute values:
$S=V \times t$
$104607.36= 4.4704 \times t$
Solve for $t$:
$t=23400$ seconds $\approx 390$ minutes
