Starting at home, nadia traveled uphill to the grocery store for 30 minutes at just 4 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 grocery store and back?

6 mph

Step-by-step explanation:

1. Get the distance traveled uphill:

4miles * 30minutes / 60minutes = 2 miles

2. Get the total distance traveled:

2miles * 2 = 4 miles

3. Get the time it took to travel back:

2miles * 60minutes / 12miles = 10 minutes

4. Get the average speed:

Total time: 30min + 10 min = 40 min

Total distance: 4 miles

Speed: 4miles * 60minutes / 40minutes = 6mph

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
