Marta is cutting a 16-inch and a 28-inch submarine sandwich for a party. How long is the longest possible piece if she cuts them all to be the same length

i can't see the picture : /

step-by-step :

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
