Question

distance from the start to each pole. the data table below measurements:

cars position time to reach pole (s) distance from start (m)
starting pole 0 0
pole 1 4 44
pole 2 8 88
pole 3 12 132
pole 4 16 176

what is the average speed of the car between the starting 4?
$\boxed{}$ $\frac{\text{m}}{\text{s}}$

Explanation:

Step1: Identify time and distance

Time at starting pole: \( t_1 = 0 \) s, distance \( d_1 = 0 \) m.
Time at pole 4: \( t_2 = 16 \) s, distance \( d_2 = 176 \) m.

Step2: Calculate total distance and time

Total distance \( \Delta d = d_2 - d_1 = 176 - 0 = 176 \) m.
Total time \( \Delta t = t_2 - t_1 = 16 - 0 = 16 \) s.

Step3: Use average speed formula

Average speed \( v = \frac{\Delta d}{\Delta t} = \frac{176}{16} \).

Step4: Compute the result

\( \frac{176}{16} = 11 \).

Answer:

11
