Question 7 - Problems - Chapter 2¶
Problem:¶
On one occasion a tidal wave (tsunami) originating near Java (Jakarta) was detected in the English Channel 32 hours later
Question:¶
Roughly measure the distance from Java to England by sea (around the Cape of Good Hope) on a map of the world, and calculate the average speed of the tidal wave.
Solution:¶
You can measure rouchly the distance on this link
Distance $s = 34000$ km
Time $t = 32$ hours
Average speed $v = \frac{s}{t} $ km/h
In [1]:
import numpy as np
Distance = 34000
Time = 32
Average_speed = Distance / Time
# limit to 2 significant figures as distance is given in 2 significants too
print(f'The average speed in km per hour is {Average_speed:.0f} km/h.')
