Answer:
The first claim is false. Natural resources can most definitely exist without synthetic products.
Explanation:
All synthetic products are derived from natural resources as everything has to come from a source in the beginning. However, most natural resources themselves are the source, make sense? For example, water is a naturally occurring resource, but even water is derived from specific components, however it doesn't need anything synthetic to exist. Now take hairspray, to make hairspray you need water and synthetic resources, see where I'm going with that?
Answer: 120 mph or 2 mpm
Explanation: 60/5= 12
12*10=120mph
Going 10 miles in 5 minutes means you would be able to go 20 miles in 10 minutes. You would have a total of 12 five minute blocks at 10 miles each. 60 miles in 30 minutes or 120 in 60 minutes.
Or 10 miles in 5 minutes would be 2 miles in 1 minute. (10/5=2)
