You are asked to find how long it takes a given amount of a substance to burn and you are given the rate at which the substance burns.  Convert the mass in grams to moles and use a dimensional analysis setup: mol C4H10 X (1 min/0.240 mol C4H10).

15 / (12*4 +1*10) = 0.258621 moles

By ratio :

x min/0.258621 moles = 1/0.240

Hence, x = 1.0776 minutes.
