You can put this solution on YOUR website! Sally and Rocky travel toward each other from 350 km apart.
Sally is biking at 90km/h and Rocky at 110 km/h.
If they started at the same time, how many hours later will they meet?
--------
Draw the picture.
They are nearing one another at 90+110 = 200 km/h
-------
Equation:
time = distance/rate
time = 350/200 = 7/4 = 1 3/4 hrs
