What are the two numbers?
Word Problem
A bridge is built across a river. One quarter of the bridge is over the left bank of the river and one third of the bridge is over the right bank. The river is 120 m wide. How long is the bridge?
Let the larger number be L and the smaller be S.
ReplyDeleteGiven:
L + S = 50
When L is divided by S, the quotient is 4 and the remainder is 5, so:
L = 4S + 5 (and S > 5)
Substitute into the sum:
(4S + 5) + S = 50
5S + 5 = 50
5S = 45
S = 9
Then:
L = 4(9) + 5 = 36 + 5 = 41
The two numbers are 41 and 9.
