To find out how long it will take to cover 8 miles at a speed of 40 miles per hour (mph), you can use the formula:
Time = Distance / Speed
In this case, the distance is 8 miles and the speed is 40 mph.
Plugging in the values:
Time = 8 miles / 40 mph
Calculating this gives:
Time = 0.2 hours
Now, to convert hours into minutes (since there are 60 minutes in an hour):
0.2 hours x 60 minutes/hour = 12 minutes
Therefore, if you are traveling at a speed of 40 mph, it will take you approximately 12 minutes to go 8 miles.
