Question

Charles is training for a race he runs 4/5 of a mile everyday how many miles does he run in 8 days

Answer 1

we are given that a person runs 4/5 of a mile per day, that is:

$N=\frac{4}{5}\text{ miles/day}$

To determine the number of miles he runs in 8 days, we need to multiply the number of miles per day by 8, that is:

$n=\frac{4}{5}\text{ miles/day(8days)}$

Solving we get:

$n=\frac{32}{5}\text{ miles}$

in decimal notation this is:

$n=6.4\text{ miles}$
