We know that the ride that Rohan wants to take lasts for 3 minutes, and goes up to maximum speed of 75 miles per hour
We have to find the domain and range
Domain: all possible values of the independent variable
Range: all possible values of the dependent variable
In this situation, the independent variable is time and the dependent variable is speed
Hence,
Domain = [0,3] minutes
Range = [0,75] miles per hour
