Question 903085
Use good written language with the needed punctuation:


<i>A man travels a distance of 250 km. He travels 150km by bus and 100km by train and takes 3hrs. If he travels 100km by bus and 150 km by train, he takes 2:50hrs,  then what is the speed of train and bus ?</i>


r for rail speed
b for bus speed


FIRST TRAVEL PATH
{{{TIME=DISTANCE/RATE}}}
{{{highlight(150/r+100/b=3)}}}


SECOND TRAVEL PATH
Again {{{T=D/R}}}---- do not confuse this R with r.
{{{highlight(100/r+150/b=2&5/6)}}}


Two equations in the two unknown variables r and b.
Solve the two equations as a system.


You might be able to setup a data table.  I set up the two equations without a data table, since this seemed easier to do without one.
