I believe it’s 12 minutes since the since the time is unknown, you set it up as x/20+x/30 since you know that they are being added. Filling up the canteen is 1 because you want it full all the way so you find the common denominator and solve for the x which is 12

Which trigonometric functions always have values less than 1? Explain your answer.
raketka [301]

Answer:

Notice that the values of sine and cosine are between 0 and 1. You found them by dividing the length of a leg by the hypotenuse. The hypotenuse is the longest side, so the numerator is less than the denominator. That means the output of the sine or cosine function is always less than 1.
