If you look at a unit circle (or you have one memorized, which I would strongly suggest) (√2/2,√2/2) is located at the radian value
, which is 45 degrees
The traveling speed of each ship is :
- Ship A = 24 mph
- Ship A = 24 mphShip B = 26 mph
Distance apart at 12:00 noon = 176 miles
Recall :
Distance = speed × time
Ship A :
Departure time = 9AM
Speed = s
Travel time = 12 - 9 = 3 hrs
Distance covered = 3 × s = 3s
Ship B :
Departure time = 8AM
Speed = 2+s
Travel time = 12 - 8 = 4 hours
Distance = 2+s(4) = 8 + 4s
Distance apart = 3s + (8 + 4s)
176 = 3s + 8 + 4s
176 = 7s + 8
176 - 8 = 7s
168 = 7s
s = 168 / 7
s = 24
Ship A speed = s = 24mph
Ship B speed = s + 2 = 26 mph
