Consider the following cash flows of two mutually exclusive projects for Spartan Rubber Company. Assume the discount rate for both projects is 10 percent.

Year	Dry Prepreg			Solvent Prepreg
0	$	1,730,000		$	765,000
1		1,103,000			390,000
2		906,000			630,000
3		753,000			396,000

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.)
