a boat is moving at 3 meters/sec one boy wieghs 65 kgjumps off the front at 2 m/s. the second boy jumps out of the back of the boat, he wieghs 68kg and jumps at a speed of 4 m/s. if the boats mass is 100kg. what is the velocity of the boat.
what i did was multiply 65 times 2 to get...
If the average speed going to town is 40km/hr, and return at an average speed of 60 km/hr. what is the average speed? why is it not 50 km/hr
Is the answer 30? because he goes 40 km/hr for 1 1/2 hours. etc.
