Let A,B and C be 100-digit numbers,where A=22... 2, B=33... 3, and C=66... 6.What is the value of the product B and C in terms of A?

Two cars travel toward each-other from two cities A and B,which are 195 km apart.They travel at rates of 25 km and 40 km an hour respectively.If they start at the same time,how soon will they meet?

Note that B = (3/2)A and C = 3A, BC = (3/2)A * 3A = (9/2)A^2


distance = rate * time
and the sum of their distances = 195
Let t be the time,
25 km *t + 40 km * t = 195 km
65 km * t = 195 km
t = 3 hours
