A coach at a track meet measured the time of a runner every 10 meters (m) during a 100 m dash the data for the runner are shown which statement is the best analysis of the data for the runner

Because they're in different places for this the temperature varies.

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.
