1.6 miles

Answer 1

To find out how much more of the race Trey has left, we need to calculate the total distance of the race and subtract the distance he has already run.

If Trey has completed 0.25 of the race and has already run 1.2 miles, we can set up the equation:

Total distance of the race - Distance already run = Distance left

Let's call the total distance of the race 'x'.

0.25x - 1.2 = Distance left

Since we want to find out how much more of the race Trey has, we can solve for 'Distance left'.

0.25x - 1.2 = Distance left

To solve for 'x', we can add 1.2 to both sides of the equation:

0.25x - 1.2 + 1.2 = Distance left + 1.2

0.25x = Distance left + 1.2

0.25x = Distance left + 1.2

Now, we need to find the value of 'x'.

If Trey has already run 1.2 miles, the distance he has left is the total distance of the race minus 1.2 miles.

Distance left = x - 1.2

Let's substitute that value into our equation:

0.25x = x - 1.2 + 1.2

0.25x = x

Now, we have:

x = 4

Therefore, the total distance of the race is 4 miles.

To find out how much more of the race Trey has, we can subtract the distance he has already run (1.2 miles) from the total distance of the race (4 miles):

4 - 1.2 = 2.8 miles

So, Trey has 2.8 miles more of the race left.
