Question

The depth of the Mariana Trench in the Pacific Ocean is reported to be approximately 3.62×104
feet deep. The depth of the Grand Canyon is approximately 6.09×103
feet deep.

Approximately how many times deeper is the Mariana Trench than the Grand Canyon, to the nearest whole number?

Answer 1

(3.62×10^4) / (6.09×10^3) = (3.62/6.09)×10 ≈ 5.94 ≈ 6

So the Mariana Trench is about 6 times deeper than the Grand Canyon (to the nearest whole number).
