Question

1. If a spring stretches 35 inches when 65 pounds is attached, then how far will it stretch when 42

pounds is attached?

Answer 1

Set up a ratio with x being the unknown distance:

35/65 = X/42

Cross multiply:

65x = (35*42)

Simplify:

65x = 1470

Divide both sides by 65:

X = 1470 / 65

X = 22.615

It will stretch 22.615 inches ( Round the answer as needed.)
