Answer:
C. 7 hours
Step-by-step explanation:
Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...
distance = speed × time
300t = 350(t -1)
300t = 350t -350 . . . . eliminate parentheses
350 = 50t . . . . . . . . . . add 350-300t
7 = t . . . . . . divide by 50
The trip out took 7 hours.
60 / 5 = 12 miles per gallon
36 miles = 12 miles / gal * x gallons
divide by 12
36/12 =x gallons
3 =x
He needs 3 gallons
Answer:
890.625
Step-by-step explanation:

Answer:
x1 = 1/2 + 1/2t
x2 = 4 -2t
x3 = t
Step-by-step explanation:
Your answer is correct as far as it goes. The values of x1 and x2 also need to be expressed in terms of t.
x1 = 1/2 + 1/2t
x2 = 4 -2t
x3 = t
