A marathon is 131/5 miles long. If 4 people divide up the distance equally, how many miles does each person need to run?

disa [49]

Answer:

$6\frac{11}{20}\ mi$

Step-by-step explanation:

we know that

A marathon is 131/5 miles long

If 4 people divide up the distance equally,

then

Divide the total distance by 4

$\frac{(131/5)}{4}=\frac{131}{20}\ mi$

Convert to mixed number

$\frac{131}{20}\ mi=\frac{120}{20}+\frac{11}{20}=6\frac{11}{20}\ mi$
