One-fifth of the length of a foot-race is 3 miles. Find the length of the race

15

Step-by-step explanation:

3x5 is equal to 15

sorry if I am wrong I am just a 6th gradrr

let's call the entire length of the foot race we are looking for:  d

for distance.

We can then rewrite this problem as:

One-third of  d

is 5 miles. What is  d .

When dealing with fractions in this way the word "of" means to multiply. So we can write this problem in algebraic form as:

1 3 × d = 5

We can multiply each side of the equation by  

3  to solve for  d

while keeping the equation balanced:

3 × 1 3 × d = 3 × 5

3 3 × d = 15  1 × d = 15 d = 15

The length of the race is 15 miles.
