Both speakers describe the asteroid that hit Earth and caused a massive extinction, including the decimation of dinosaurs. The speakers describe the size of this asteroid in different terms. Summarize each speaker’s description and explain which one gives you a better picture of the size of this asteroid.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
