Question

1/) Joe and Jerry went for a bike trek during nthe holidays. On the first day they rode 1/3 of the total distance. On the second day they were tired and only rode 1/4 of the remaining distance. On the third day they rode half of the distance left. The last day they rode the remaining 18 km. How far did they ride together?
2.) George has three as many marbles as Sam. If George gives 5 of his marbles to Sam, George will have twice as many marbles as Sam. How many marbles does Sam have?

Answer 1

3rd and 4th days ... 18 km + 18 km = 36 km

36 km = 3/4 d after 1st day ... d = 48 km

48 km = 2/3 total d ... total d = 72 km


G = 3 S

G - 5 = 2 (S + 5) ... G = 2 S + 15
