At 9: 00 on saturday morning, two bicyclist pass each other on a bicycle path. the bicyclist heading north is riding 5km/h faster then the bicyclist heading south. at 10: 30, (1.5 hours later) they are 49.5 km apart. find the two bicyclists’ rates.

Step-by-step explanation:

One rider's rate is xthe other is x+4

Once they pass each other, they travel for 1.5 hrs...and the combined distance they travel = 39 km

SoRate x Time = Distanceand we have

x(1.5) + (x+4)(1.5) = 39 simplify

1.5x + 1.5x + 6 = 39

3x + 6 = 39 subtract 6 from both sides

3x = 33 divide by 3 on both sides

x = 11 km/hr this si the slower rider's rate

x + 4 = 11 + 4 = 15 km/hr and this is the faster rider's rate

can you me with homework?

what is the answer?
