Question 1198586
The tall ship makes the trip in 10 hours to yacht makes the trip in 2.5 hours the tall ship is 30 kn slower than the art for each boat the trip time multiplied by the speed equals distance traveled you know both boats will travel the same distance how fast does each boat traveling in knots nautical miles per hour
:
   Try to make this more understandable.
The tall ship makes the trip in 10 hours.
The yacht makes the trip in 2.5 hours.
The tall ship is 30 kn slower than the yacht.
For each boat the trip time multiplied by the speed equals distance traveled. 
Know both boats will travel the same distance.
How fast does each boat traveling in knots, nautical miles per hour?
:
let d = the distance both vessels travel
Write a speed equation, speed = dist/time
first, find the distance in nautical miles
Yacht speed - tall ship speed = 30
{{{d/2.5}}} - {{{d/10}}} = 30
multiply both sides by 10, cancel the denominator and you have
4d - d = 10(30)
3d = 300
d = 300/3
d = 100 n mi
:
Find the speed of each
100/2.5 = 40 knots, yacht speed
100/10  = 10 knots, tall ship speed
