At 9: 00 o saturday morning two bicycylist heading in oppisite directions pass eachother on a bicycle path. the bicyclist heading north is riding 4km/hr faster that the bicyclist heading south. at 10: 30, they are 39 km apart. find the two bicyclists rates.

39/1.5=26 for the 1.5 hours difference.

divide 26/2=13 for each person.

divide 4/2 for the speed increase of person north. The speeds much average to 13.

subtract 13-2=11 and add 13+2=15 for south and north.

north speed is 15 km per hour and south is 11 km per hour.

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol

you can use a^2+ b^2=c^2
