You can put this solution on YOUR website! boat heads north at 30 mph while a steamer heads east at 40 mph at the same time.
When is the distance between them 50 mi?
:
let t = time (hrs) that they are 50 mi apart
Use pythag here; a^2 + b^2 = c^2; dist = speed * time
(30t)^2 (40t)^2 = 50^2
900t^2 + 1600t^2 = 2500
It's obvious that t = 1 hr
