Josie is training for a race. The ratio of the number of minutes to the number of miles she runs is 24 to 3. She plans to run 10 miles. How many minutes will it take her?

80 minutes

Step-by-step explanation:

The ratio of the number of minutes to the number of miles she runs is 24 : 3.

i.e 24 miles in 3 minutes

Average speed = 24 miles/3minutes

= 8 miles per minute

Since, she plans to run 10 miles, her average speed will be:

= 8 miles per minute x 10 miles

= 80 minutes

Thus, it will take Josie 80 minutes to go run 10miles

126 maybe. sorry

answer:

at time x=0 we have 1000, at time x=1 we have 2000, at time x=2 we have 4000.  

so that's an initial value of 1000 and a ratio of 2,

y = 1000 (2^x)

hope this !
