Question

find the speed a car will travel with a hear ratio 3.2 with 27 invhes diameter tores a 2690 rpm. Round to the nearest mph

Answer 1

62 mph

Explanation:

We can use the formula:

v = (rpm * pi * d * hr) / (63360 * 12)

where v is the speed of the car in miles per hour (mph), rpm is the engine speed in revolutions per minute, d is the diameter of the tire in inches, and hr is the gear ratio.

Substituting the given values, we get:

v = (2690 rpm * pi * 27 inches * 3.2) / (63360 * 12) = 61.7 mph

Rounding this value to the nearest mph, we get that the speed of the car will be approximately 62 mph.
