Answer:

1.6 jumps/seconds.

Explanation:

Given the following data;

Total number of jumps = 144 jumps

Time = 90 seconds

To find the average jump rate;

Average \; jump \; rate = \frac {Total \; number \; of \; jumps}{Time}

Substituting into the formula, we have;

Average \; jump \; rate = \frac {140}{90}

Average jump rate = 1.5555 ≈ 1.6 jumps/seconds.
