d) -90º
Step-by-step explanation:
Do the same process for each of the 3
you have miles per how many minutes and you need miles per hour
you know 60 minutes make 1 hour convert the minutes to hours
this will gives you miles per equivalent hour
you need miles per 1 hour
Here is number 1
1) 5 miles in 20 minutes
5 miles in (20/60) hr = 5 miles in 1/3 hr
to get 1 hr multiply by 3
equation so keep the balance
5 * 3 = 15
rate = 15 miles per hour.
same process for the others
