WILL GIVE BRAINLIEST

Answer 1

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

Answer 2

Hi there!

My name is Chris and I'll be helping you today!

So your question states that a boat departed the port at 36.8 km/h.

After 1.75 hours, a second boat emerges from the port.

After 1.8 hours, the second boat is 86.9 km away from the first boat.

Also, remember that speed equals distance over time.

Therefore, your answer will be: The speed boat's speed in km/h was 24.3 km/h. Forgive me if I am incorrect.

Enjoy your day!
