Daniel rollerbladed 3 miles in 12 minutes what was his speed in miles per hour
2 answers:
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
15mi per hr
60/12=5
3mi • 5 = 15
