Answer

Explanation:

Step1: Recall speed formula

The formula for speed is $v=\frac{d}{t}$, where $v$ is speed, $d$ is distance and $t$ is time.

Step2: Calculate speed for hopping 5m

For hopping over a distance $d = 5$m and time $t=4.02$s, $v=\frac{5}{4.02}\approx1.24$m/s.

Step3: Calculate speed for hopping 10m

For hopping over a distance $d = 10$m and time $t = 6.72$s, $v=\frac{10}{6.72}\approx1.49$m/s.

Step4: Calculate speed for walking backwards 5m

For walking backwards over a distance $d = 5$m and time $t=4.39$s, $v=\frac{5}{4.39}\approx1.14$m/s.

Step5: Calculate speed for walking backwards 10m

For walking backwards over a distance $d = 10$m and time $t = 10.03$s, $v=\frac{10}{10.03}\approx0.99$m/s.

Step6: Calculate speed for regular walking 5m

For regular - walking over a distance $d = 5$m and time $t=3.47$s, $v=\frac{5}{3.47}\approx1.44$m/s.

Step7: Calculate speed for regular walking 10m

For regular - walking over a distance $d = 10$m and time $t = 7.61$s, $v=\frac{10}{7.61}\approx1.31$m/s.

Step8: Calculate speed for speed - walking 5m

For speed - walking over a distance $d = 5$m and time $t=3.05$s, $v=\frac{5}{3.05}\approx1.64$m/s.

Step9: Calculate speed for speed - walking 10m

For speed - walking over a distance $d = 10$m and time $t = 5.45$s, $v=\frac{10}{5.45}\approx1.83$m/s.

Answer:

Task Distance Time Speed
Hopping 5 m 4.02 s 1.24 m/s
Hopping 10 m 6.72 s 1.49 m/s
Walking Backwards 5 m 4.39 s 1.14 m/s
Walking Backwards 10 m 10.03 s 0.99 m/s
Walking Regular 5 m 3.47 s 1.44 m/s
Walking Regular 10 m 7.61 s 1.31 m/s
Speed Walking 5 m 3.05 s 1.64 m/s
Speed Walking 10 m 5.45 s 1.83 m/s
