Darren Drives to school in rush hour traffic and average 42 mph. He returns home mid-afternoon when there is less traffic and averages 48 mph. What is the distance between his home and school if the total traveling time is 1 hr 15 min ?

7,24

step-by-step explanation:

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

noncoplanar points are points that do not lie on the same line.
