Answer:
360 seconds ....
Step-by-step explanation:
Y = mx + b
slope(m) = 3/4
(-8,7)...x = -8 and y = 7
now we sub and solve for b, the y int
7 = 3/4(-8) + b
7 = - 6 + b
7 + 6 = b
13 = b
so ur line is : y = 3/4x + 13
He uses 15 gallons. Because 270/6 = 45. Meaning he drives 45 miles per gallon. So 675/45=15. 15 gallons he will need to use to drive 675 miles.
Let x be the number of hours that both will be the same.
27.5x = 23.25x + 17
27.5x - 23.25x = 17
4.25x = 17
x = 17 ÷ 4.25
x = 4
Ans: 4 hours
