There is a cart on which put the tank at the point 6 m away from the pond.
Taro repeats the work of carrying water full in the vessel to transfer to the tank on the cart after drawing water from the pond and returning to the pond.
Although 2L of water can be put into a vessel, there is a hole in the vessel leaking 20 cm3 of water in one second.
The speed of Taro is 90 m/m when he carries water and returns to the pond.
The cart begins to move in the direction of an arrow at 30 m/m at the same time he leaves a pond first.
This work will be finished, when a vessel will become empty by the time he arrives at the cart.
The tank shall not be filled with water during the work and it shall not take time to draw or transfer water.
Answer to the following questions.
(1) Find the volume of the water which can be put into the tank at the 1st time and the 2nd time, respectively.
(2) When I finally finish transferring water, find the volume of the water in the tank.
Moreover, find the distance from the pond to the cart at that time.
