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

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

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
