Answer:
0.6 hours
Step-by-step explanation:
Let's say J is Jen's speed (cake pops per hour), and let's say M is Maryna's speed (cake pops per hour).
Let's say there are 12 cake pops total that need to be made. Jen made half of the cake pops in 3 hours, so she made 6 cake pops in 3 hours. So her speed is 2 cake pops per hour.
Then, Jen and Maryna made the other half of the cake pops in 1/2 hour. Therefore, their combined speed is:
J + M = 6 cake pops / (1/2 hr)
J + M = 12
2 + M = 12
M = 10
So Maryna can make 10 cake pops per hour.
If Maryna was working alone, the amount of time it would take her to make 6 cake pops is:
6 cake pops / (10 cake pops per hour) = 0.6 hours
It would take 0.6 hours, or 36 minutes.
Answer:
6 
Step-by-step explanation:
you are adding 3 1/4 to 3 1/4 which is 6 2/4 or 6 1/2
or you can multiply 13/4 by 2 to get 26/4 or 13/2 which, again, is 6 1/2
If it flies at a rate of feet per hour, then it will will travel a foot per hour
