Question

PLZ HELP!!

Answer 1

It takes 1 hour to get to work.

It takes 20 minutes to get to the train station, and the rest of the trip is spent on the train that takes him to work.  That means he is on the train for 40 minutes.

20 minutes is equal to 1/3 hour and 40 minutes is 2/3 hour

So from home to train station:

1/3 hour * 42mph = 14 miles

And from train station to work:

2/3 hour * 60mph = 40 miles

So how far does Mark live from his work place?

14 + 40 = 54 miles

Answer 2

Mark lives 20 minutes away
