You would need to set up a formula here for simple interest (non-compounding)

interest = principle X interest X term

the amount of interest earned is the future value (ending value) minus the previous value or 7,300-6000 = 1,300 in interest

Then we need to find out how many years it would take to earn that amount

1,300 = (6,000 *.055) * x

1,300=330x

then isolate x 1,300/330=x

x = 3.9 or about 4 years
