The length of a rectangular field is 75 meters. Its width is 15 meters. Sofie ran around the track 3 times. How far did she run?
What is 540 meters (15*2+75*2)*3 = 540 OR we don't know because there isn't enough information given relating the track to the field. Correct response is up to the quiz master.

An electric pump takes 3 hrs to fill a tank, but due to a leak in the tank now it takes 3 and 1/2 hrs to fill the tank. If the tank is full, how much time(in hrs) will the leak require to empty that tank? the leak is such that fluid exits at a constant rate, AND the leak is at the bottom of the tank so it WILL empty completely.
21 hours. Ro = V/3 3.5= V/(Ro-Rleak) sub and solve.

Remember the game 24? you're given 4 integers and you may ONLY add, subtract, multiply and divide to get them to equal 24. each number may only be used once. e.g. 1,1,1,8; (1+1+1)*8 = 24. So try: 1, 8, 12, 12
