8 miles = 12874.8m 
Total distance = 16 miles = 25749.5m 
 time = distance/velocity
 First instance, t =12874.8/24
  = 536.45 
 Second instance, t = 12874.8/30
  = 429.16 
 Total time = 536.45 + 429.16 = 965.61 
 Average velocity = Total distance / Total time
  = 25749.5/965.61
  = 26.67 m/s

A sailboat travels a distance of 600 m in 40 seconds. What speed is it going?
Gekata [30.6K]

Answer:

15 miles /seconds

Explanation:

Distance = 600m

Time = 40 seconds

Speed=?

speed =  \frac{distance}{time}  \\ speed =  \frac{600}{40}

Simplify

\frac{600}{40}  =  \frac{60}{4}  \\  = 15
