A bus left new york city and arrived in Philadelphia after 2 1/3 hours. From there, it took 1 3/4 hours to travel Baltimore. It took another 5/6 hour to go from baltimore to washington. If the bus arrived in washington at 10:05 pm, at what time did it leave New York city

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
