Two people take identical Jet Skis across a river, traveling at the same speed relative to the water. Jet Ski A heads directly across the river and is carried downstream by the current before reaching the opposite shore. Jet Ski B travels in a direction that is 35° upstream and arrives at the opposite shore directly across from the starting point.

(a) Which Jet Ski reaches the opposite shore in the least amount of time?

(b) Confirm your answer to part (a) by finding the ratio of the time it takes for the two Jet Skis to cross the river.
