Answer 1

The entire race is 26.20 miles long.

Explanation:

Given that:

Sam is 18.34 miles in the race.

This length represents the 70% of the entire length of the race.

Let,

x be the total length of the race.

70% of x = 18.34

`(70)/(100)x=18.34\\`

0.7x = 18.34

Dividing both sides by 0.7

`(0.7x)/(0.7)=(18.34)/(0.7)\\x=26.20`

Hence,

The entire race is 26.20 miles long.
