| May 18, 2021 | education
The distance between the coast of Chile and the islands of Japan is 16,000 km.
In order to determine the time it takes for a tsunami to reach the shores of Japan, it is necessary to divide the distance between these points by the tsunami speed, which, according to the condition of the problem, is 750 km / h.
In this case, we get:
16000/750 = 21 1/3 hours.
In 1 hour – 60 minutes, so the exact time will be:
21 hours + 1/3 * 60 minutes = 21 hours + 60/3 minutes = 21 hours 20 minutes.
Answer: Tsunami will reach Japan in 21 hours and 20 minutes.
