Question

A 280-inch pipe is cut into two pieces. One piece is three times the length of the other. Find the length

of the shorter piece.
What’s the length (in inches) of the shorter piece

Answer 1

70 inches

Explanation:

The pieces are in the ratio ...

shorter : longer = 1 : 3

so the shorter piece is 1/(1+3) = 1/4 of the total length. Its length is ...

(1/4)(280 in) = 70 in
