Jessica b
Exercise 4F Q1 answer done out please

anyone have this question done in the oliver murphy fundamental applied maths 2nd edition book? Cant figure out where ive gone wrong:grimacing:

There is an error in the question Jessica....he can't land 75m downstream with the given speeds. When you try and solve the question you get a value for the sine of an angle greater than 1....which is impossible.
I got 36 and 82 seconds in one version of rounding trying to get the answer.
