C Correct answer
Explanation

Speed = 36 km/hr. Distance = 36 * 4 = 144 km. 1 km is approximately 0.621371 miles. 144 * 0.621371 = 89.47 miles, which is approximately 90 miles.

AI explanation

To find the distance in kilometers first, use the formula distance equals speed multiplied by time. Multiplying 36 kilometers per hour by 4 hours gives a distance of 144 kilometers, and since the conversion rule is 8 kilometers equals 5 miles, we set up the proportion 144 multiplied by 5 divided by 8. This calculation results in 90 miles, meaning the car covers 90 miles.
