Question 13 - Problems - Chapter 2

Problem:

The speed-skating record for women is held by Bonnie Blair, who completed a 500-m race in 39.10 s.

Question:

a) What is the corresponding average speed in m/s?

b) And in km/h.

Solution:

Distance $s = 500$ m

Time $s = 39.10$ s

Average speed $v = \frac{s}{t}$

In [1]:
Distance = 500 # in m
Time = 39.10 # s
Avg_Speed = Distance / Time# m/s
print(f'The average speed is {Avg_Speed:.1f} m/s or {Avg_Speed*3.6:.1f} km/h.')

The average speed is 12.8 m/s or 46.0 km/h.
