Acar traveling 70 miles per hour travelled one hour longer than a truck traveling 60 miles per hour. if the car and truck travelled a total of 330 miles, for how many hours did the car and truck travel all together?

5

Step-by-step explanation:

60 x + 70(x+1)=330

60x+70x+70=330

130x=260

x=2

x+1=3

so the answer is 5 hope i helped <33

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

i believe the correct answer is b.
