To protect her new two-wheeler, Iroda Bike buys a length of chain. She finds that its linear density is 0.88 lb/ft. If she wants to keep its weight below 1.9 lb, what length of chain is she allowed?

To solve for the length that is allowable, we simply take the ratio of the maximum allowable mass (1.9 lb) and the linear density. That is:

maximum allowable length = 1.9 lb / (0.88 lb / ft)

maximum allowable length = 2.16 ft
