Question

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?

Answer 1

Answer:

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.
