Question 12 - Problems - Chapter 2

Problem:

In setting a world record for speed, the horse Big Racket ran 402m (1/4mile) in 23.8 s.

Question:

What was its average speed?

Solution:

Distance $s = 402$ m

Time $s = 23.8$ s

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

Distance = 402 # in m
Time = 23.8 # 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 16.9 m/s or 60.8 km/h.
