How do you do 4b? I understand that t=3.0833 but don't get the rest. I feel as if I'm missing something really obvious?!

4. type that figure into your calculator, and press equals. press the hollow circle then the three commas (about the ENG button) and it comes out as 3^0 4^, 59.88 ish which basically means 3 hours 4 minutes and 59.88 seconds so basically 3 hours 5 minutes which is the proof, so you got it correct! well done
