Question

Please tell me the answers for number 6 part a and b even though i did it

Answer 1

Part A is 1 Hour and 35 Minutes
Part B is 7:05pm 
To get Part B it's 45 minutes later so:
60 - 20 = 40minutes
So we know that Amar needs 40 minutes to get to 7pm
Then we have 5minutes left over because 45-40=5
So we add that and we have 7:05pm.
