Question 630771
There isn't a boat in the world let alone a tugboat that can go 180 miles in 10 minutes.
There isn't a car in the world that can go that fast.
You will be hard pressed to find a plane that can go that fast. Most commercial planes go about 500 mph.
10 minutes not 10 hours. Yet you have mph miles per hour.
10 minutes is 1/6 hour
r*t=d
r=d/t
r-c=180/1/6 =1080
r+c=180/1/12=2160
add them
2r=3240
r=1620
1620-1080=c=540
1620+c=2160
c=2160-1620=540
