None. Minutes are a unit of time, miles are a unit of distance.The time taken to cover 397 miles would depend on your average speed.
2.4 minutes
If you are traveling at 268 mph, you will cover 40 miles in about 8 minutes 57 seconds.
Then your speed is precisely (70 miles per 200 minutes).If you do the division of (70/200), you find the more familiar unit rate:(70 miles / 200 minutes) = 0.35 mile/minute = 21 miles/hour .
Average speed is: (distance covered) divided by (time to cover the distance) Your speed is exactly 10 miles per 10 minutes. To get it in other units that sound more familiar, notice that 10 miles in 10 minutes is 1 mile per minute. There are 60 minutes in 1 hour, so you would be able to cover 60 miles in that time. 10 miles/10minutes = 60 mph.
distance/speed = time 19/40 = 0.475 hours = .475 x 60 minutes = 28.5 minutes
A plane traveling at a speed of 200 mph for 30 minutes would cover a distance of 100 miles.
That depends on the average speed. At 60 mph, you'll cover that in 2 hours and 5 minutes.
This question seem open ended because it was not specific. However, it takes an average of 7-10 minutes to cover a 4 miles journey depending on your drive speed. Whilst, it takes an average of 80-84 minutes of walk to complete a 4 miles distance.
If you maintained an average speed of 45 mph, the time to cover 2 miles would be about 2 minutes and 40 seconds.
If you run 2.5 miles in 20 minutes your average speed is 7.5 miles per hour.
