b) 2 feet, 7 1/2 inches
c) 2 feet, 7 3/4 inches
d) 3 feet, 8 1/2 inches

Answer 1

To find out how much farther you jumped this week compared to last week, subtract the length jumped last week from the length jumped this week. The correct answer is 2 feet, 4 inches.

Step-by-step explanation:

To find out how much farther you jumped this week compared to last week, you need to subtract the length jumped last week from the length jumped this week. First, convert the lengths to a common unit of measurement, such as inches. The length jumped this week is 17 feet + 5 1/4 inches, which is equal to 17 * 12 + 5 1/4 * 4 = 205 inches. The length jumped last week is 14 feet + 9 3/4 inches, which is equal to 14 * 12 + 9 3/4 * 4 = 177 inches. Subtracting the length jumped last week from the length jumped this week, we get 205 inches - 177 inches = 28 inches. This is equivalent to 2 feet, 4 inches. Therefore, the correct answer is b) 2 feet, 4 inches.
