A tiger in a zoo has consumed 66 pounds of food in 11 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 90 pounds?
| 4 | |
| 13 | |
| 6 | |
| 9 |
If the tiger has consumed 66 pounds of food in 11 days that's \( \frac{66}{11} \) = 6 pounds of food per day. The tiger needs to consume 90 - 66 = 24 more pounds of food to reach 90 pounds total. At 6 pounds of food per day that's \( \frac{24}{6} \) = 4 more days.

What is the distance in miles of a trip that takes 2 hours at an average speed of 65 miles per hour?
| 400 miles | |
| 160 miles | |
| 130 miles | |
| 390 miles |
Average speed in miles per hour is the number of miles traveled divided by the number of hours:
speed = \( \frac{\text{distance}}{\text{time}} \)Solving for distance:
distance = \( \text{speed} \times \text{time} \)
distance = \( 65mph \times 2h \)
130 miles
How many 2 gallon cans worth of fuel would you need to pour into an empty 20 gallon tank to fill it exactly halfway?
| 10 | |
| 5 | |
| 8 | |
| 7 |
To fill a 20 gallon tank exactly halfway you'll need 10 gallons of fuel. Each fuel can holds 2 gallons so:
cans = \( \frac{10 \text{ gallons}}{2 \text{ gallons}} \) = 5
