Step-by-step explanation: Victor jumps farther than Meg.
If Victor jumps 9 feet and 2 inches and Meg jumps 7 feet and 4 inches, that means that Victor jumps 1 foot 10 inches farther than Meg.
Lets learn our conversations: 1 foot = 12 inches
If Victor jumps 9 feet, that means that 9 feet = 108 inches + 2 inches, which equals 110 total inches jumped.
If Meg jumps 7 feet, that means that 7 feet = 84 inches + 4 inches, which equals 88 total inches jumped.
110 - 88 = 22 inches.
So, Victor jumped 22 inches farther than Meg, or 1 foot and 10 inches farther than Meg.
