What is the distance in miles of a trip that takes 9 hours at an average speed of 75 miles per hour?
| 45 miles | |
| 300 miles | |
| 150 miles | |
| 675 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 = \( 75mph \times 9h \)
675 miles
A menswear store is having a sale: "Buy one shirt at full price and get another shirt for 25% off." If Frank buys two shirts, each with a regular price of $23, how much will he pay for both shirts?
| $25.30 | |
| $24.15 | |
| $40.25 | |
| $17.25 |
By buying two shirts, Frank will save $23 x \( \frac{25}{100} \) = \( \frac{$23 x 25}{100} \) = \( \frac{$575}{100} \) = $5.75 on the second shirt.
So, his total cost will be
$23.00 + ($23.00 - $5.75)
$23.00 + $17.25
$40.25
A tiger in a zoo has consumed 24 pounds of food in 4 days. If the tiger continues to eat at the same rate, in how many more days will its total food consumtion be 54 pounds?
| 9 | |
| 3 | |
| 8 | |
| 5 |
If the tiger has consumed 24 pounds of food in 4 days that's \( \frac{24}{4} \) = 6 pounds of food per day. The tiger needs to consume 54 - 24 = 30 more pounds of food to reach 54 pounds total. At 6 pounds of food per day that's \( \frac{30}{6} \) = 5 more days.
15 members of a bridal party need transported to a wedding reception but there are only 3 4-passenger taxis available to take them. How many will need to find other transportation?

There are 3 4-passenger taxis available so that's 3 x 4 = 12 total seats. There are 15 people needing transportation leaving 15 - 12 = 3 who will have to find other transportation.
