Question

Storms in the South Pacific can create waves that travel all the way to the California coast, which are 12,000 km away. How long does it take them if they travel at 15.0 m/s?

a) 800,000 s
b) 80,000 s
c) 8,000 s
d) 800 s

Answer 1

To calculate the time it takes for the waves to travel from the South Pacific to the California coast, we can use the formula: time = distance / speed. In this case, the distance is 12,000 km and the speed is 15.0 m/s.

The correct answer is 800,000 s.

Step-by-step explanation:

To calculate the time it takes for the waves to travel from the South Pacific to the California coast, we can use the formula: time = distance / speed. In this case, the distance is 12,000 km and the speed is 15.0 m/s. However, we need to convert the distance from kilometers to meters, so the distance becomes 12,000,000 meters. Using the formula, the time it takes for the waves to travel this distance is:

time = 12,000,000 m / 15.0 m/s = 800,000 s.

Therefore, the correct answer is a) 800,000 s.

To calculate the time it takes for the waves to travel from the South Pacific to the California coast, we can use the formula: time = distance / speed. In this case, the distance is 12,000 km and the speed is 15.0 m/s.
