How long will it take to drive 325 miles at 70 miles per hour?

Answer 1

70 miles per hour... 70 * 4 hours = 280 miles. That leaves 45 miles @ 70 miles per hour.

70 / 60 = 1.167 miles per minute. 1.167 * 45 miles = 52.515 minutes

So all together - 4 hours 52.515 minutes to travel 325 miles @ 70 miles per hour.

Actually it would be more accurate if you simply

60/70 = 0.86 miles per minute. 0.86 * 45 miles = 38.57 minutes

Total time all together would be 4 hours 38.57 minutes

Answer 2

To work this out divide 325 by 70.

It would take about 4 hours 38.57 minutes.
