4 miles in 18 minutes = 13.33... miles per hour.
It is: 4.8 mph
2.4 miles in 21 minutes = 0.114286 miles per minute or 6.8571428... mph
6 mph, six miles per hour.
In this problem, the unit rate is the rate of speed. speed = distance/time = 60 miles/70 min = 0.86 mi/min (rounded)
50 mph at that rate of travel.
speed = distance/time = 2.8mi/30min = 0.09mi/min
The time it takes to walk 0.44 miles depends on an individual's walking speed. On average, people walk at a pace of about 3 to 4 miles per hour. At this rate, it would take approximately 6 to 8 minutes to walk 0.44 miles.
If you walk at the average pace which is 3 miles an hour, it takes 20 minutes for 1 mile. So do the math. 30 times 20 = 600, divide that by 60 minutes in an hour, and you get 10 hours exactly. So therefore, I do not recommend walking that far. (:
