City M is 600 km from City N. A bus drives 60 km/h and a truck drives 50 km/h along the road between City Mand City N. How
long after the truck should the bus start driving if they want to
meet in the midpoint of the road?

After  2h  s

Step-by-step explanation:

The  the  whole  journey  is  600  km  from  city  M  to  N.  So  the  mid  point  would  be  300  km

The  bus  takes  5  h  to  reach  the  mid point  of  the  road  (  300  km  ÷ 60  km/h  =  5  h)

And  the  truck  takes  6  h  to  reach  the  mid  point  of  the  road  (  300 km  ÷  50  km/h  =  6  h)

So  if  they  want  to  meet  each  other  the  bus  should  start  its  journey    one  hour  after  the  truck.
