Given that we know the map scale and the distance in the map, we want to find the distance between the starting line and the 1st aid station, we will see that the distance is 31 miles.
So the scale of the map is:
2 in = 50 miles.
This means that a distance of 2 inches in the map is equivalent to 50 miles in the reality.
And we know that, in the map, there is a distance of 1.25 inches.
Now let's return to the scale:
2 in = 50 miles.
Dividing both by 2, we get:
(2 in)/2 = (50 miles)/2
1 in = 25 mi
Now we can rewrite the distance in the map as:
1.25 in = 1.25*( 1 in)
And we know that 1 in = 25 mi, then we can write:
1.25 in = 1.25*( 1 in) = 1.25*( 25 mi) = 31.25 mi
Rounding to the nearest mile, we get 31 miles.
So the distance between the starting line and the 1st aid station is 31 miles.

Scale ratios are used to represent measurement of different units
The bike is at 31 miles from the starting line
The scale is given as:
2 inches = 50 miles
Double quotes i.e. " represents inches.
So, 1.25" means 1.25 inches
Multiply both sides of the equation 2 inches = 50 miles by 1.25
[tex]2 \times 1.25 inches = 50 \times 1.25 miles[/tex]
Divide both sides of the equation by 2
[tex]1.25 inches = 25 \times 1.25 miles[/tex]
Multiply 25 and 1.25
[tex]1.25 inches = 31.25 miles[/tex]
Approximate
[tex]1.25 inches = 31miles[/tex]
Hence, the bike is at 31 miles from the starting line
