0.80>0.79 Option A is the correct answer
To find a speed in miles per hour, we need to divide a number of miles by a number of hours.
We are given 48 miles, so we already have a number of miles.
We are given the time as 1 hour and 12 minutes. We need to convert this time into hours.
1 hour + 12 minutes = 1 hour + 12/60 hour = 1.2 hours
speed = distance/time = 48 miles / 1.2 hours = 40 mph
Answer: The fourth choice, 40 mph.

The true inverse funtion is f(x) aka f of x. g(x) is not an inverse function
