Question

PLEASE I HAVE TO GET THESE RIGHT!!!!! i NEED HELP! IM STUCK!!!!!!!

Answer 1

Inversely proportional:

y = constant/x, or y*x = constant. Let's see which give the *same* product:

a) 6*1.5 = 5*1.25 NO
b) 5*2 = 4*3 NO
c) 4*2.25=6*1.5  YES!!!
d) 4.5*3 = 6*4 NO

So, C)!!!

Answer 2

a. 6 mph for 1.5 hours and 5 mph for 1.25 hours
9 miles, 6.25 miles
b. 5 mph for 2 hours and 4 mph for 3 hours
10 miles, 12 miles
c. 4 mph for 2.25 hours and 6 mph for 1.5 hours
9 miles, 9 miles
d. 4.5 mph for 3 hours and 6 mph for 4 hours
13.5 miles, 24 miles
C.) would be the best choice here as the amount of time is inversely proportional to the jogging rate; however, the route is always the same distance. C.) is the only option where the distances are equal, and is the best choice as such.
