To find out how long it takes to drive 40 miles at a speed of 60 miles per hour (mph), you can use the formula: time = distance ÷ speed.
In this case, the distance is 40 miles and the speed is 60 mph. So, you would calculate:
Time = 40 miles ÷ 60 mph
This simplifies to:
Time = 2/3 hours
To convert 2/3 of an hour into minutes, you multiply by 60 (since there are 60 minutes in an hour):
2/3 × 60 = 40 minutes
Therefore, it will take you approximately 40 minutes to drive 40 miles at a speed of 60 mph.
