The answer is in the "Miles per hour" (Mph) you drove. If you
drove 40 Mph, then in one hour you would have driven 40 miles.
Therefore, in five hours, at the constant speed of 40 Mph, you
would have drive 200 miles.
It depends on the speed of the vehicle as well as the miles
driven. At 60 miles per hour (or a mile a minute), it would take 19
minutes. At 30 miles per hour, driving 19 miles would take 38
minutes. In this case, the formula would be:
time = speed in minutes X miles driven.
