Will and Grace are canoeing on a lake.  Will rows at 50 meters per minute and Grace rows at 20 meters per minute. Will starts rowing at 2 p.m. from the west end of the lake, and Grace starts rowing from the east end of the lake at 2 p.m. If they always row directly towards each other, and the lake is 3800 meters across from the west side of the lake to the east side, at what time will the two meet?

Since they are rowing towards each other, their combined speed is:

50 + 20 = 70 meters per minute 

 

3800 / 70 =54 + 2/7 minutes after 2:00 p.m. when they will meet.
