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
Cheers,
