Answer:
The bus left New York city at 5:10pm
Step-by-step explanation:
First, we need to calculate the total number of hours the bus used to travel from New York to Washington.
Total number of hours traveled
= 2 1/3hr + 1 3/4hr + 5/6hr
= 7/3+7/4+5/6
=28+21+10/12
=59/12
= 4 11/12hours
Converting 11/12hours to minutes we will have 11/12×60 = 55minutes
Therefore the bus traveled for 4hours 55minutes.
If the bus arrived in Washington at 10:05 pm and the bus left New York 4hours 55minutes ago, this means that the bus did left New York at (10.05-4.55)pm i.e 5:10pm
4hours past 10:05pm will be 6:05pm
55minutes past 6:05pm will be 5:10pm
This means that the bus left New York city at 5:10pm
