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 at 5 m

Substitute $d = 5$ m and $t=4.02$ s into the formula: $v=\frac{5}{4.02}\approx1.24$ m/s.

Step3: Calculate speed for hopping at 10 m

Substitute $d = 10$ m and $t = 6.72$ s into the formula: $v=\frac{10}{6.72}\approx1.49$ m/s.

Step4: Calculate speed for walking backwards at 5 m

Substitute $d = 5$ m and $t=4.39$ s into the formula: $v=\frac{5}{4.39}\approx1.14$ m/s.

Step5: Calculate speed for walking backwards at 10 m

Substitute $d = 10$ m and $t = 10.03$ s into the formula: $v=\frac{10}{10.03}\approx0.99$ m/s.

Step6: Calculate speed for regular walking at 5 m

Substitute $d = 5$ m and $t=3.47$ s into the formula: $v=\frac{5}{3.47}\approx1.44$ m/s.

Step7: Calculate speed for regular walking at 10 m

Substitute $d = 10$ m and $t = 7.61$ s into the formula: $v=\frac{10}{7.61}\approx1.31$ m/s.

Step8: Calculate speed for speed - walking at 5 m

Substitute $d = 5$ m and $t=3.05$ s into the formula: $v=\frac{5}{3.05}\approx1.64$ m/s.

Step9: Calculate speed for speed - walking at 10 m

Substitute $d = 10$ m and $t = 5.45$ s into the formula: $v=\frac{10}{5.45}\approx1.83$ m/s.

Answer:

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