Using the world map, determine the distance in parallel 40 ° s. w. from the Pacific coast of South America

Using the world map, determine the distance in parallel 40 ° s. w. from the Pacific coast of South America to the islands of New Zealand. Calculate how long the tsunami off the coast of South America reaches New Zealand if its speed of propagation is 800 km / h

Longitude of the western part of South America at 40 ° S. w. – 74 ° W
Longitude of New Zealand – 178 ° East
Distance in degrees (180 – 74) + (180 – 178) = 108 °
1 ° parallels in 40 ° S equal to 85.4 km, 108 * 85.4 = 9223 km
9223/800 = 11.5 hours
