To calculate the number of minutes in 20 miles, you can use the following formula:
( \text{Time (minutes) = Distance (miles) / Speed (mph) } )
First, we need to know the distance in miles and the speed in miles per hour (mph) for the given route. Once we have that information, we can plug it into the formula to get the estimated time in minutes. Please provide the distance and speed values, and I can assist you with the calculation.
