Simon whitfield victoria, british columbia, won the men's triathlon at the sydney olympics. the race consisted of 1.5 km swim in sydney harbour, a 40 km bike ride, and a 10km run.
a) what percent is each component ?
b) what percent of the race distance is spent on land?
(p. s all these questions are from a text book and are question i don't understand, so explain your answer.)
: )

Total triathlon distance →1.5 km + 40km  + 10 km = 51.5 km

So 51.5 km represents 100% of distance covered.

The % of each component = (distance of component/Total distance) multiplied by 100% so :

% of swim → (1.5 / 51.5) × 100 → 0.029 × 100 = 2.9%

% of bike ride → (40 / 51.5) × 100 →0.776 × 100 = 77.6%

% of  run → (10 / 51.5) × 100 → 0.194 × 100 = 19.4%

Percentage spent on land  will be

(40 km bike ride + 10 km run / Total triathlon distance) multiplied by 100%

(50 / 51.5) × 100 → 0.970 ×100 = 97%

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
