A. 20 minutes
B. 27 minutes

C. 1 hour, 24 minutes

D. 3 hours


can you get me started on this?

Answer 2

I do not know you work with pounds, Euros or dollars. Let's use dollars.

If you have 12 dollars, and you have 9 dollars left.
Then you have spent 12-9=3 dollars.
The percentage spent is 3/12*100=25%
i.e.
amount spent/original amount*100%

The percentage of the amount left is, similarly,
9/12*100=75%, or
amount left/original amount * 100%

Answer 3

Suggestion: if you have a different problem, you are better off posting a new thread.

Paddling problem:
If the Jim and John paddle towards each other, the relative speed is the sum of the two, namely 4+5=9.
The lake is three mile wide, so time taken should be 3/9 hour= 1/3 hour=20 minutes.
