Freddie is walking for a charity at a constant rate. After two hours, Freddie has walked 4 miles. At 4 hours, he had walked 8 miles. Write an equation to find the total distance, y, after x hours. How long will it take Freddie to walk 25 miles?

Freddie would have walked 25 miles after 12 and a half hours.

Step-by-step explanation:

Given that Freddie is walking at a constant speed, and after 2 hours he walked 4 miles, while after 4 hours he walked 8 miles, to determine how long he walked 25 miles, the following calculation must be performed:

4/2 = Miles per hour

2 miles per hour

2X = Y

2X = 25

X = 25/2

X = 12.5

Therefore, Freddie would have walked 25 miles after 12 and a half hours.

you can't solve x because it is 2 linear equation and you only have one equation
