A Leisure Time Cruise riverboat travels 46 km downstream in
A Leisure Time Cruise riverboat travels 46 km downstream in 2 hr. It travels 51 km upstream in 3 hr. Find the speed of the boat and the speed of the plane.
Solution
speed * time =distance
 also written as r*t=d
 We know the time and the distance
 Surely, if I told you that I went 60 miles in one hour you would say that I went 60 mph.
 x*1=60
 x=60
 or if I told you that I went 120 miles in 2 hours you would know I went 60 mph.
 x*2=120
 x=60 again
 But something is wrong with your problem.
 It says\"Find the speed of the boat and the speed of the plane. \"
 There is no plane mentioned.
 r*2=46
 r=? You can solve this!
 and the other
 r*3=51
 r=51/3=?
 so it should current not plane the current is 3
 20+3=23
 20-3=17
