Final answer:
Talia's jumping speed is calculated by dividing her total number of jumps (879) by the total time taken (403 seconds), which equals approximately 2.18 jumps per second.
Step-by-step explanation:
The student asks about the speed at which Talia is jumping rope. To find the speed, we need to divide the total number of jumps by the total time.
Talia jumps 879 times in 403 seconds. To find her jumping speed, we do the following calculation:
Speed = Total jumps ÷ Total time = 879 jumps ÷ 403 seconds ≈ 2.18 jumps per second.
So Talia is jumping at an approximate speed of 2.18 jumps per second.
