Dinosaurs have been extinct for about 6.5x10^7 years, while Neanderthals have been extinct for 3.0 x 10^4 about years. About how many times longer have dinosaurs been extinct than Neanderthals?

Answer 1

To find out how many times longer dinosaurs have been extinct than Neanderthals, we can divide the time dinosaurs have been extinct by the time Neanderthals have been extinct.

6.5 x 10^7 / 3.0 x 10^4
= 2.167 x 10^3

Therefore, dinosaurs have been extinct approximately 2,167 times longer than Neanderthals.
