Lindsay and Lorraine are trying to match the jump rope world record. Together, they need to jump 48 times in a row. Lindsay has
gotten 14 jumps in a row, and Lorraine has gotten 13. How many more jumps (j) do they need to match the record?
1 answer:
Answer: 21
Step-by-step explanation:
Given : Lindsay and Lorraine are trying to match the jump rope world record.
Number of jumps they need to jump together in a row = 48
Lindsay has gotten 14 jumps in a row, and Lorraine has gotten 13.
Total jumps = 14+13=27
Let 'j' be the number of more jumps they need to match the record.
j= Total jumps needed - Total jumps they already gotten
⇒ j= 48-27
⇒ j= 21
Hence, they need 21 more jumps to match the record.
