In a race that consisted of three parts, the cycling part was 12 1/2 miles long. the running part of the rase was 1/4 the distance of the cycling part. the kayaking part of the race was 1/2 the distance of the running part. what was the entire distance in miles of the race

The cycling part was 12 1/2 miles long.

Hence the distance covered by cycling is 12.5 miles

The running part of the race was 1/4 the distance of the cycling part.

The running part is 0.25 of the cycling part.

So running part = 0.25 × 12.5 = 3.125 miles

The kayaking part of the race was 1/2 the distance of the running part.

So kayaking part is 0.5 of the running part.

So kayaking part = 0.5 × 3.125 = 1.5625 miles

Hence the total distance

= 12.5 + 3.125 + 1.5625

=17.1875 miles

The entire distance in miles of the race is 17.1875 miles

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

no one knows lol
