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

u dumb boi

step-by-step explanation:

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
