t takes Carlos 9 minutes to drive from home to work at an average rate of 22 miles per hour.
We can use this information to determine the distance to work
First we'll have to convert 9 minutes to 9/60 hours (simplify to get: 3/20 hours)

distance = (rate)(time)
So, distance = (22)(3/20 hours) = 66/20 = 33/10 miles

How many minutes will it take Carlos to cycle from home to work along the same route at an average rate of 6 miles per hour?
time = distance/rate
So, time = (33/10)/6 = (33/10)(1/6) = 33/60 HOURS = 33 MINUTES

Answer: B
