Question

Whale sharks swim forward while ascending or descending. They swim along a straight-line path at a shallow angle as they move from the surface to deep water or from the depths to the surface. In one recorded dive, a shark started 50 m below the surface and swam at 0.85 m/s along a path tipped at a 13 ∘ angle above the horizontal until reaching the surface. How much time did this motion take?

Answer 1

I hope I've interpreted this situation correctly

Answer 2

anyway, the first step is to find the distance the shark travels by setting up a trig ratio that involves the hypotenuse of this triangle (the distance swam), the angle (13 degrees), and the opposite side (50, the depth of the water)



then, once you have the distance, d = rt, where d is the distance swum, r is the speed (0.85m/s), and t is the time. solving for time should give the desired solution
