Question

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?

Answer 1

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
