Question 1198586
<br>
A less traditional method for solving the problem, which requires less work....<br>
The distances for the tall ship and yacht are the same, and the ratio of times is 4:1; that means the ratio of speeds is 1:4.  So
let x = speed of tall ship in knots
then 4x - speed of yacht in knots<br>
The difference in speeds is 30 knots:<br>
4x-x=30
3x=30
x=10<br>
ANSWERS:
The speed of the tall ship is x=10 knots
The speed of the yacht is 4x=40 knots<br>
