Question 20 - Problems - Chapter 2

Problem:

Carl Lewis set an Olympic record for the 100-m run in 1991 with a time of 9.86 s.

Question:

What was his average speed?

Solution:

Distance $s = 100$ m

Time $t = 9.86$ s

Time = 9.86 #s
Distance = 100 # in m
Speed = Distance / Time
print(f'His average speed was {Speed:.1f} m/s. (or {Speed*3.6:.1f} km/h).')

His average speed was 10.1 m/s. (or 36.5 km/h).
