Answer:
10 hours
Step-by-step explanation:
Two boats leave a port at the same time, one going north and the other traveling south.
<u>Southbound boat rate</u> = 40 mph
The northbound boat travels 18 mph faster than the southbound boat.
<u>Northbound boat rate</u> = 40 + 18 = 58 mph
Two boats rate = 40 + 58 = 98 mph (this means they are apart 98 km after one hour)
Total distance = 980 miles
Total rate = 98 mph
Time
hours
Please look up "volume of a cylinder."
The formula for the volume of a cylinder of radius r and height h is
V = pi*r^2*h
So, if r = 1.5 m and h = 10 m, the volume of the tank is
V = pi*(1.5 m)^2*(10 m) = 70.69 cubic meters.
