Starting at home, emily traveled uphill to the hardware store for 60 minutes at just 6 mph. she then traveled back home along the same path downhill at a speed of 12 mph. what is her average speed for the entire trip from home to the hardware store and back?

Answer

The average speed is not just the average of 666 mph and 121212 mph.

Hint #22 / 12

She traveled for a longer time uphill (since she was going slower), so we can estimate that the average speed is closer to 666 mph than 121212 mph.

Hint #33 / 12

To calculate the average speed, we will make use of the following:

avaerage speed: total distance/total time

What was the total distance traveled?

total distance

=distance uphill+distance downhill

=2×distance uphill

distance uphill

=speed uphill×time uphill

=6 mph×60 minutes×  

60 minutes

1 hour

/60 minutes=6 miles

Substituting to find the total distance:

total distance=12

What was the total time spent traveling?

total time=time uphill+time downhill

ANd u keep on going im not going to answer it all so it dont look like copy paste but the answer is:

The average speed is 8 mph, and which is closer to 6mph than 12mph as we expected.
