Give the step-by-step reasoning process and then the final answer. If you take the fastest speed of a rabbit and double it, add 4 to that then double it again you get 188. How fast is the rabbit?
You doubled a number to get 188 so in reverse, you would divide by 2 so 188 / 2 = 94. You added 4 to this number and in reverse, you would subtract by 4 so 94 - 4 = 90. You doubled a number to get 90 so in reverse you would divide by 2 so 90 / 2 = 45 is the fastest speed.
The final answer: 45.
