1. two boats a and b depart from a port at the same time, travels to the north at 15 miles per hour, while b travels eastward at 20 mph. how fast boats are separated two hours after they left the port?

50 mi

Step-by-step explanation:

Two hours after leaving port,

The triangle formed by their tracks and the line joining their current positions is a right-angled triangle.

According to Pythagoras,

        a² + b² = c²

   30² + 40² = c²

900 + 1600 = c²

            2500 = c²

     √(2500) = c

                    c = 50 mi

The boats will be separated by 50 mi two hours after leaving port.

i believe it is 0.1m because the measurement of 30.4m limits how precise you can be

you can only be as precise as the least precise measurement
