Jet Ski A heads directly across the river and is carried downstream by the current before teaching 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. (Note: Angles are measured relative to the X axis shown in Example.)

(a) Let both have velocity v m/s
Width of the stream is w
as A is heads directly across the river time required to travel. w will be w/v s
Now B is 35* towards up stream, v cos 35* is towards across the river. he will w / (v cos 35) s
w / (v cos 35) is > w/v
so jet ski A reaches the opposite shore in the least amount of time ans.
(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.
...... (jet ski A/jet ski B) = ( w/v ) / ( w/v cos 35) = cos 35 = 0.82
time for A/ time for B = 0.82
