where d is the stopping distance in feet and r is speed of the car in miles per hour.
The stopping distance is 75 feet, we have to find the speed of the car,
Putting d = 75 in the equation, we get,

Thus, the car was moving approximately at a speed of 37.74 miles per hour.
The fraction would be 37 out of 42. You basically divide the two and get something around 88%.
