A rabbit and a hedgehog had a race around a 550m long circular track. Both ran at constant speed. The rabbit's speed was 10m/s, and the hedgehog's speed was 1m/s. They started at the same time. However, the hedgehog ran in the opposite direction to the rabbit. When they met, the hedgehog immediately turned round and ran after the rabbit. How long after the rabbit did the hedgehog reach the finish? 45 sec 50 sec 55 sec 100 sec 505 sec

One of the actions that are proposed to favor the increase in the percentage of renewable energies used in the economy is to promote the production of vegetables that can be used in energy generation, taking advantage of the surplus of organic matter generated during the process of photosynthesis, but respecting, in the first place, agri-food needs. The figure shows the dimensions of an ABC triangular-shaped field that is used to plant different types of vegetables. Through a DE segment parallel to the BC side, you want to divide the area into two parts with the same area, so that one is dedicated to sowing products to manufacture energy and another to sow products for human consumption.
