Dinosaurs have been extinct for about 6.5x10^7 years, while Neanderthals have been extinct for about 3.0x10^4 years. About how many times longer have dinosaurs been extinct than Neanderthals?

Question

A.
1,000 times longer

B.
2,000 times longer

C.
10,000 times longer

D.
20,000 times longer

Answer 1

The difference in time between dinosaurs and Neanderthals being extinct can be calculated by dividing 6.5x10^7 by 3.0x10^4:

(6.5x10^7) / (3.0x10^4) = 2166.67

This means that dinosaurs have been extinct about 2166.67 times longer than Neanderthals. Rounding this to the nearest whole number, the answer is:

B. 2,000 times longer
