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 + 20.2km + 5.3km
total distance = 25.8km

To fill a 12 gallon tank exactly halfway you'll need 6 gallons of fuel. Each fuel can holds 1\(\frac{1}{2}\) gallons so:

cans = \( \frac{6 \text{ gallons}}{1\frac{1}{2} \text{ gallons}} \) = 4

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 = \( 70mph \times 8h \)
560 miles

If 38% of the town's 19,000 voters cast ballots the number of votes cast is:

(\( \frac{38}{100} \)) x 19,000 = \( \frac{722,000}{100} \) = 7,220

The mayor got 74% of the votes cast which is:

(\( \frac{74}{100} \)) x 7,220 = \( \frac{534,280}{100} \) = 5,343 votes.

Diane scored 83% on the test meaning she earned 83% of the possible points on the test. There were 240 possible points on the test so she earned 240 x 0.83 = 200 points. Each question is worth 4 points so she got \( \frac{200}{4} \) = 50 questions right.
