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
