The rate is 3 and 1
percent of 21 over 300 = 7%% rate:= 21/300 * 100%= 0.07 * 100%= 7%
7(21) / 4
(21/4)*7 = 36.75 parts
distance = rate * time 7 miles = 20 mph * t t = 7 miles / 20 mph = .35 hours = 21 minutes
If you continue your rate of 5.25 an hour, you will eat 36.75 in 7 hours.
The change in distance divided by the change in time. (21-7 miles)/(3-1 hours)=14/2=7 miles/hour or 7 mph.
