Answer: the answer is d
Step-by-step explanation:
3.75 mi in 3 hours
you need to do 3.75÷3=
and you get 1.25 mi an hour
now you need to do the next one
it is 7.5 mi in 6 hours
so, you're going to do 7.5÷6=
and we get 1.25 mi an hour
now let's do the last one
12 mi in 8 hours
you're going to do 12÷9=
and you get 1.5 mi in an hour
so, the 3 hours and 6 hours are proportional
therefore, the answer is d) No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.
hope this helps!!
