Use good written language with the needed punctuation:
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 ?
r for rail speed
b for bus speed
FIRST TRAVEL PATH
SECOND TRAVEL PATH
Again ---- do not confuse this R with r.
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.
