To calculate the time it takes to drive a certain distance at a given speed, you can use the formula: time = distance ÷ speed.
In this case, the distance is 20 miles and the speed is 65 miles per hour (mph). Inserting these values into the formula gives us:
time = 20 miles ÷ 65 mph = 0.3077 hours.
To convert hours into minutes, multiply by 60:
0.3077 hours × 60 minutes/hour = 18.46 minutes.
Therefore, it takes approximately 18.5 minutes to drive 20 miles at 65 mph.
