Last week, Juliet ran 22 kilometers. ​ ​This week, she plans to run 2\frac{2}{5}2 5 2 ​ times as far as last week. ​ ​How many kilometers does Juliet plan to run this week?

52.8 kilometers

Step-by-step explanation:

This week she plans to run 2²/₅ times as much as last week.

If she ran 22 kilometers last week, then multiple 22 by 2²/₅ to find out the number of kilometers to run this week.

First convert the improper fraction to a proper one:

2²/₅ = 12/5

= 12/5 * 22

= 264/5

= 52.8 kilometers

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

only 10/60 isn't equivalent

hope this : )
