How many 1\(\frac{1}{2}\) gallon cans worth of fuel would you need to pour into an empty 6 gallon tank to fill it exactly halfway?
| 9 | |
| 3 | |
| 4 | |
| 2 |
To fill a 6 gallon tank exactly halfway you'll need 3 gallons of fuel. Each fuel can holds 1\(\frac{1}{2}\) gallons so:
cans = \( \frac{3 \text{ gallons}}{1\frac{1}{2} \text{ gallons}} \) = 2
14 members of a bridal party need transported to a wedding reception but there are only 3 3-passenger taxis available to take them. How many will need to find other transportation?
| 5 | |
| 9 | |
| 3 | |
| 6 |
There are 3 3-passenger taxis available so that's 3 x 3 = 9 total seats. There are 14 people needing transportation leaving 14 - 9 = 5 who will have to find other transportation.
A tiger in a zoo has consumed 15 pounds of food in 3 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 45 pounds?
| 9 | |
| 6 | |
| 2 | |
| 1 |
If the tiger has consumed 15 pounds of food in 3 days that's \( \frac{15}{3} \) = 5 pounds of food per day. The tiger needs to consume 45 - 15 = 30 more pounds of food to reach 45 pounds total. At 5 pounds of food per day that's \( \frac{30}{5} \) = 6 more days.
A triathlon course includes a 100m swim, a 30.1km bike ride, and a 8.100000000000001km run. What is the total length of the race course?
| 24.8km | |
| 63.6km | |
| 60.4km | |
| 38.3km |
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 100 meters to kilometers, divide the distance by 1000 to get 0.1km then add the remaining distances:
total distance = swim + bike + run
total distance = 0.1km + 30.1km + 8.100000000000001km
total distance = 38.3km
