Answer:
140 minutes
Step-by-step explanation:
After 28 mins you've gone 4 miles, assuming this rate is constant and you dont slow down or speed up, in order to get to 20 miles you will have run 5x as much (20/4 = 5), thus 5x the amount of time (28x5).
20/4 = 5
5x28 = 140

Answer:
=2.4x-4.4
Step-by-step explanation:
did the test
0.3(4x-8)-0.5(-2.4x+4)
=1.2x-2.4-0.5(-2.4x+4)
=1.2x-2.4+1.2x-2
=2.4x-4.4
