The coach recorded how fast her runners ran 1 mile. Eric ran a mile in 10.84 minutes, Kay ran a mile in 12.79 minutes, and Rosie ran a mile in 9.58 minutes. How many more minutes did Eric run than Rosie?

1.26 minutes

Step-by-step explanation:

The runners all ran the same distance of 1 mile.

Eric's time to run 1 mile = 10.84 minutes

Kay's time to run 1 mile = 12.79 minutes

Rosie's time to run 1 mile = 9.58 minutes

This implies that Rosie is the fastest runner among the three.

The difference between Eric and Rosie's time = Eric's time - Rosie's time

                                            = 10.84 - 9.58

                                            = 1.26

The difference between Eric and Rosie's time shows the minutes Eric ran more than Rosie. Therefore, Eric ran 1.26 minutes more than Rosie.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
