Use this diagram to answer the questions.1. How long does it take for a primary wave to travel 2,000 km? about 4 minutes about 5 minutes about 10 minutes about 11 minutes 2. How long does it take for a secondary wave to travel 2,000 km? about 4 minutes about 5 minutes about 10 minutes about 11 minutes 3. How far does a secondary wave travel in 10 minutes? about 2000 km about 3000 km about 3500 km about 4000 km 4. How far does a primary wave travel in 10 minutes? about 2000 km about 3000 km about 3500 km about 4000 km 5. What happens to the time difference between primary and secondary waves as the distance traveled gets longer? it increases it decreases it stays the same it increases then decreases 6. Suppose a primary wave and a secondary wave both travel a distance of 4,000 km before they are picked up by a seismograph. Which wave will arrive first? primary wave secondary wave they will arrive at the same time 7. What will be the time difference between these two waves at 4,000 km? 10 minutes 11 minutes 22 minutes 23 minutes 8. Suppose both a primary wave and secondary wave start together and travel for 5 minutes. Which wave will travel farther?
