Terrance and jesse are training for a long distance race. terrance trains at a rate of 6miles every half hour, and jesse trains at a rate of 2miles every 15 minutes. a. what is the unit rate in miles per hour for each runner? b. how long will each person take to run a total of 50 miles at the given rates? c. sandra runs at a rate of 8 miles in 48 minutes. how does her unit rate compare to tarrance's and to jesse's?

Terrence trains at a rate of 6 miles every half hour:

(6 miles)/(1/2 hours) = 6/(1/2) mph = 6*2 mph = 12 mph

Jesse trains at a rate of 2 miles every 15 minutes:

(2 miles)/(15/60 hours) = 2/(1/4) mph = 2*4 mph = 8 mph

The unit rate for Terrence is 12 mph.

The unit rate for Jesse is 8 mph.

Sorry if i am wrong

answer: a.   one is a factor of every whole number since every number is divisible by itself.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.
