Bernie drove from his house to his cousin's house in 6 hours at an average rate of 52 miles per hour he drove home at an average rate of 60 miles per hour how long did it take him to drive home

7.5

Step-by-step explanation:

You have to divide the miles by the hours drived and then divide 60 per the miles per hour

5.2 hours, or 5 hours 12 minutes

Step-by-step explanation:

The distance is the same in both cases. Since distance = rate (time),

time = distance / (rate).

Here, (6 hr) (52 mph) = (time) (60 mph, or

312 mi = (60 mph) (time), which gives us

(time) = (312 mi) / (60 mph) = 5.2 hours, or 5 hours 12 minutes
