To find out how many times longer dinosaurs have been extinct than Neanderthals, we can divide the number of years dinosaurs have been extinct by the number of years Neanderthals have been extinct:
6.5 x 10^7 / 3.0 x 10^4 = 2.16666667 x 10^3
Therefore, dinosaurs have been extinct approximately 2,167 times longer than Neanderthals.
Dinosaurs have been extinct for about 6.5x10^7 years, while Neanderthals have been extinct for about 3.0 x10^4
years. About how many times longer have dinosaurs been extinct than Neanderthals?
