Answer:
I think it would be 13 feet
Step-by-step explanation:
12*5=60
and sense it is a triangle you divide by 2 and get 30
<h3>30-12-5=13</h3><h3>this is what I think</h3>
First, you do 18 miles times 3 hours.
The answer is 54
The you do 15 miles time 2 hours
The answer is 30
You can add them all up and get 84 miles total. (D)
Distance = r x t ===> t=d/r
Distance (after 2 hours driving @30mil/hr) = 2 x 30 = 60 Mil
To drive same distance (60) with r = 50, the time needed is 60/50 =1.2 hrs
