Will give brainliest will give brainliest and 50 points out of a port departed a steam boat with a speed of 36.8km/h. in 1.75 hours out of the same port and going the sam direction departed a speed boat. in 1.8 hours after the the department of the speed boat, the distance between the speed boat and the steam boat was 86.9km(the speed boat is behind the steam bat)what was the speed boats speed in km/h?

Something wrong w my ans be4? if u double-post by mistake, i can report it so u can get ur pts back! :)

speed boat departed 1.75 hrs after steam boat
1.8 hrs after speed boat departure, steam boat has sailed for a total: 1.8+1.75 = 3.55 hrs
steam boat's speed is 36.8 km/hr, so it has traveled: 3.55*36.8 = 130.64 km
speed boat is 86.9 km behind steam boat
so it is 130.64-86.9 = 43.74 km from port
speed boat's speed = 43.74/1.8 = 24.3 km/hr
