Megan drove from her house to work at an average speed of 45 miles per hour. the drive took her 20 minutes. if the drive home took her 30 minutes and she used the same route in reverse, what was her average speed going home?

Speed = distance/time  

distance = 45 miles  

time = 30 minutes = 1/2 hours  

therefore speed = 90 mph  

Question 2  

distance = speed x time  

speed = 7.5  

time = 15 minutes = 1/4 hours  

therefore distance = 15/4 miles  

time = distance/speed  

distance = 15/4 miles  

speed = 8  

time = (15/4)/8 = 15/32 hours

Step-by-step explanation:

the answer is 3/5

step-by-step explanation:

first divide 24 divided by 8 because that is the least common multiple

then divide 40 by 8

then you will get 3/5.

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.
