Eliza jumps rope for 21 minutes, counting each jump. If she jumps at a rate of 3000 jumps per hour, how many jumps does Eliza count?

Answer :

Eliza counts a total of 1050 jumps in 21 minutes.

If Eliza jumps rope for 21 minutes and her rate is 3000 jumps per hour, you can calculate the total number of jumps as follows:

  • First, convert the 21 minutes to hours:
  • 21 minutes / 60 minutes per hour = 0.35 hours
  • Now, multiply the rate by the time to find the total number of jumps:
  • 3000 jumps per hour 0.35 hours = 1050 jumps
  • So, Eliza counts 1050 jumps in 21 minutes.
