## SOLUTION This solution is **FREE** courtesy of BrainMass!

Remember that the formula is:

Distance = (rate)(time).

If you solve this for time you get

Time = (distance)/(rate).

Your problem involves two different units of distance. We must convert miles to feet. 1 mile = 5280 ft.

The answer to your problem is then

time = 4260 ft/290400 ft/hr = .01467 hr

You can convert this to minutes by multiplying by 60. The time

would be .8801 minutes or approximately 52.8 seconds.

I hope this is helpful.
