imagine you leave the dock on a fishing boat that travels east for 30kilometers when the captain realizes he left the fishing rods on the dock it takes him 40 minutes to travel out against the current but only 20 minutes to return to the dock. calculate and explain your calculations for both the average speed and average velocity of the fishing boat in terms of kilometers per hour.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
