To add these distances, they must share the same unit so first you need to first convert the swim distance from meters (m) to kilometers (km) before adding it to the bike and run distances which are already in km. To convert 300 meters to kilometers, divide the distance by 1000 to get 0.3km then add the remaining distances:

total distance = swim + bike + run
total distance = 0.3km + 20.9km + 11.600000000000001km
total distance = 32.8km

To find the average of these 4 numbers add them together then divide by 4:

\( \frac{14 + 6 + 12 + 8}{4} \) = \( \frac{40}{4} \) = 10

The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.

If 48% of the town's 41,000 voters cast ballots the number of votes cast is:

(\( \frac{48}{100} \)) x 41,000 = \( \frac{1,968,000}{100} \) = 19,680

The mayor got 84% of the votes cast which is:

(\( \frac{84}{100} \)) x 19,680 = \( \frac{1,653,120}{100} \) = 16,531 votes.

Average speed in miles per hour is the number of miles traveled divided by the number of hours:

Solving for distance:

distance = \( \text{speed} \times \text{time} \)
distance = \( 20mph \times 7h \)
140 miles
