8 miles per hour
i broke up the 45 into 3 groups of 15
i applied 2 miles to each group (making 6 miles)
then, i added one more 15 to the other 3 which would make 60 which is equal to an hour
since each 15 has 2 miles per, i added the new 15s 2 miles to the 6 miles from the original ones.
6+2=8
8mph
hope this helpsss
