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%

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
