Question

question 3.
sofia rides her bike on different paths and records the following data:
which trials have the same average speed?
a. trial 1 and 2

Explanation:

Step1: Calculate average speed for Trial 1

Average speed formula: \(v=\frac{d}{t}\). For Trial 1, \(d = 20.0\space m\), \(t=10.0\space s\). So \(v_1=\frac{20.0}{10.0}=2.0\space m/s\)

Step2: Calculate average speed for Trial 2

For Trial 2, \(d = 15.0\space m\), \(t = 5.0\space s\). So \(v_2=\frac{15.0}{5.0}=3.0\space m/s\)

Step3: Calculate average speed for Trial 3

For Trial 3, \(d = 12.0\space m\), \(t = 4.0\space s\). So \(v_3=\frac{12.0}{4.0}=3.0\space m/s\)

Step4: Calculate average speed for Trial 4

For Trial 4, \(d = 18.0\space m\), \(t = 3.0\space s\). So \(v_4=\frac{18.0}{3.0}=6.0\space m/s\)

Answer:

Trial 2 and Trial 3 have the same average speed.
