Aperson leaves home at 8: 00 a. m. and drives to a destination at a rate of 40 mph. the person returns at a rate of 25 mph and arrives at 2: 30 p. m. how far was the destination?

recall your d = rt. distance = rate * time.

the person left at 8:00, driving at 40mph, it covered a distance of say d miles, then came back at 2:30, from 8am to 2:30 pm is 6½ hours or 13/2 hours, and it again covered the same d miles back.

if going took say t hours, then coming back must have taken the slack from 6½ and t, namely (13/2) - t.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

this is answer of 144 cubic meters
