Money : Hours

$80 : 10

So let x be the money you earn for 2.5 hours.

x : 2.5

You just need to do this: 80/(10/2.5)

= 80/4

= 20

So you earn $20 for 2.5 hours.

Answer:

$20

Step-by-step explanation:

To solve this problem, you need to first find the amount earned per hour (x), then multiply that number by 2.5 hours.

x = 80/10

x = 8

8*2.5 = 20

Randy wants to run half a marathon. Half a marathon is 13.1 miles. if she wants to run the race in 2 hours what rate(in minutes
IRINA_888 [86]

Answer:

9.16 minutes per mile

At 10 miles, she is short of her intended rate

Step-by-step explanation:

2 hours means 60 * 2 = 120 minutes

Randy aims to run 13.1 miles in 120 minutes. So to get the rate [min/mi], we must divide total minutes by total miles:

120/13.1 = 9.16 minutes per mile

Moreover, she realized at 10 miles, she has taken 90 minutes. So her rate at that point [min/mi] is:

90/10 = 9 min/mi

Well, Randy is short of her intended rate

and

4 =  {2}^{2}
