If 20 students participated in the high jump, 40 students in long-jump, and 60 students in 100-meter dash, and if 5 students participated in all three tryouts, how many students participated in only two of these tryouts? - Answer-Let x be the number who participated in exactly 1 of the tryouts, y be 2 of tryouts, z be 3 of tryouts. Then x + y + z = 90 and x + 2y + 3z = 120. It is given that z = 5, so x + y = 85 and x + 2y = 105. Thus, y = *20*

A train traveled from Station A to B at ave speed of 80 km/hr and from Station B to C at ave speed 60 km/hr. If the train didn't stop at Station B, what was the average speed at which the train traveled from Station A to C?
1) The distance that the train traveled from A to B was 4 times the distance from B to C
2) The amount of time it took the train to travel from A to B was 3 times the amount of time that it took the train to travel from B to C - Answer-*Time = Dist / Speed*
d1/80 is the amt. of time it took to travel from A to B, and d2/60 is the amt. of time it took
to travel from B to C. We want to find average speed from A to C, given by Total Dist / Total Time = (d1 + d2) / ( (d1/80) + (d2/60) )
1) gives d1 = 4d2, which plugged into the above yields an answer
