1.875 mph
1 mile in 32 minutes
= 1/32 mile in 1 minute
= 60 x 1/32 miles in 1 hour
60/32 = 30/16 = 15/8 = 7.5 /4
= (7.5 x 25)/(4 x 25) = 187.5/100 = 1.875

You would be walking at a pace of 23.8 miles per hour. This is a trick question because the first half ("If you walk three miles in 44 minutes..") is completely unrelated to the real question being "How many MPH would walking 2.10 a mile in 5.30 minutes be?" The way this answer was solved is by first finding out the fraction of hours that 5.30 minutes takes up by dividing 5.30 minutes by the number of minutes in an hour, which is 60. This gives an answer of .0883 hours. Since MPH stands for miles per hour or miles/hour, all that now needs to be done is to put 2.10 miles over .0883 hours and simplify (2.10 miles/.0883 hours). This comes out to about 23.8 miles per hour after following significant figure rules.
Average walking speed for an adult is around 4 miles per hour.
(19.76 miles)/[(42.23 minutes)/(60 minutes/hour) = 28.08 miles/hour, to the justified number of significant digits.
It depends on the speed. At 10 miles per hour 100 miles is 10 hours. At 100 miles an hour it is 1 hour. At 1000 miles an hour it is 0.1 hour (= 6 minutes).
At 1 mile per hour it is 55 hours, at 2 miles an hour it is 27.5 hours at 5 miles an hour it is 11 hours at 55 miles an hour it is 1 hour at 60 miles an hour it is 55/60 hour or 55 minutes at 120 miles an hour it is 27.5 minutes at 550 miles an hour it is 6 minutes etc
