Consider the following cash flows of two mutually exclusive projects for Spartan Rubber Company. Assume the discount rate for both projects is 12 percent.

Year	Dry Prepreg			Solvent Prepreg
0	$	1,750,000		$	775,000
1		1,105,000			400,000
2		910,000			650,000
3		755,000			400,000

a. What is the payback period for each project? (Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
