Two students walk in the same direction along a straight path, at a constant speed - one at .90 m/s and the other at 1.90 m/s.
a.) assuming that they start at the same point ant the same time, how much sooner does the faster arrive at a destination 780 m away?
b.) how far would the students have to walk so that the faster student arrives 5.50 min before the slower student?
