Full solution

Q. A group of kangaroo friends had a jumping contest and measured their jumps. Pocket jumped 1616 meters, Hopster jumped 99 meters, and Joey jumped 55 meters.\newlineFind the mean length.\newlinem
  1. Add Lengths of Jumps: Add up the lengths of all the jumps made by the kangaroo friends.\newlinePocket jumped 1616 meters, Hopster jumped 99 meters, and Joey jumped 55 meters.\newlineTotal length = 16+9+5=3016 + 9 + 5 = 30 meters
  2. Count Kangaroo Friends: Count the number of kangaroo friends who participated in the jumping contest.\newlineThere are 33 kangaroo friends: Pocket, Hopster, and Joey.\newlineNumber of kangaroos =3= 3
  3. Calculate Mean Length: Calculate the mean length of the jumps by dividing the total length by the number of kangaroos.\newlineMean length =Total lengthNumber of kangaroos= \frac{\text{Total length}}{\text{Number of kangaroos}}\newlineMean length =30 meters3= \frac{30 \text{ meters}}{3}\newlineMean length =10 meters= 10 \text{ meters}
