Look at the units! Minutes and miles per hour. Hours and minutes are both time but they are not the same.
1hour = 60minutes. We have 20 minutes.
20/60 = 1/3
So we ran for 1/3 of an hour at 5mph.
If we ran 2hours at 5 miles per hour (MPH), it's probably more obvious you ran for 10miles. That's 2 x 5. Which is Hours x MPH.
So what about our calculation? Hours x MPH = 1/3 x 5 = 1.6667 miles.
7.5 mph
2.33 miles in 20 minutes at 7.0 mph
240 miles
If you ran 10 miles in 30 minutes, you averaged 20 miles per hour. You covered the 10 miles in half an hour, so double the time and the distance, and you'll get 20 miles in 1 hour, or a 20 mph average.

about 10 miles. yep. that's it. the big 1-O
20 minutes = 20/60 hours = 1/3 hours 13 divided by 1/3 = 39 mph (wow!)
How far did I run if I ran for 20 minutes and stepped 3350 steps
aircraft (550 mph) | 17 hours 20 minutes
1.7 miles in 20 minutes equates to 5.1 mph
