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. what was the speed boats speed in km/h?

To solve this, you need to use the equation that gives the relationship between time(t), speed(s), and distance(d):

s=d/t
d=st

For the steam boat, the velocity was 36.8, and the time was 1.75 hours before the speedboat left plus the 1.8 hours after the speedboat left. Substitute this information into the equation to find the distance it travels:

d=36.8*(1.75+1.8)
d=130.64 km

According to the question, we know that the distance the speedboat travels is 86.9 km behind the steam boat. So d for the speedboat is 130.64-86.9, or
43.74 km. It is also given that the speedboat travels for 1.8 hours, so t=1.8. Substitute this information into the equation to find the speed.

s=43.74/1.8
s=24.3 km/h

So the speed of the boat is 24.3 km/h
