Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
The speed in miles per hour will be 15 miles per hour.
Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
Given that Daniel covers 3 miles in 12 minutes then the speed is calculated as:-
S = 3 / 12 = 0.25 miles per minute.
The speed in miles per hour is,
S = 0.25 x 60 = 15 miles per hour.
Hence, speed in miles per hour is 15 miles per hour.
