Final answer:
The car will take approximately 1.38 hours to travel 90 miles.
Step-by-step explanation:
The equation d = 65h describes the distance (d) a vehicle travels in h hours. To find the time it will take a car to travel 90 miles, we need to solve the equation for h.
Given that d = 90 miles, we can substitute this value into the equation: 90 = 65h.
To solve for h, divide both sides by 65: h = 90 / 65.
Using a calculator, we find that h ≈ 1.38 hours.
