The total water usage for a city is 50,000 gallons each day. Of that total, 32% is for personal use and 42% is for industrial use. How many more gallons of water each day is consumed for industrial use over personal use?
| 5,000 | |
| 9,200 | |
| 2,600 | |
| 14,499 |
42% of the water consumption is industrial use and 32% is personal use so (42% - 32%) = 10% more water is used for industrial purposes. 50,000 gallons are consumed daily so industry consumes \( \frac{10}{100} \) x 50,000 gallons = 5,000 gallons.
How many hours does it take a car to travel 40 miles at an average speed of 40 miles per hour?
| 7 hours | |
| 5 hours | |
| 1 hour | |
| 3 hours |
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 time:
time = \( \frac{\text{distance}}{\text{speed}} \)
time = \( \frac{40mi}{40mph} \)
1 hour

A tiger in a zoo has consumed 48 pounds of food in 6 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 80 pounds?
| 8 | |
| 4 | |
| 6 | |
| 9 |
If the tiger has consumed 48 pounds of food in 6 days that's \( \frac{48}{6} \) = 8 pounds of food per day. The tiger needs to consume 80 - 48 = 32 more pounds of food to reach 80 pounds total. At 8 pounds of food per day that's \( \frac{32}{8} \) = 4 more days.
