Pedestrian 6526

At 9 o'clock, the pedestrian climbed at an average speed of 5 km/h, and 3 hours later, a cyclist followed him at 12 km/h. Determine what time they will meet.


t = 14:09 h Wrong answer

Step-by-step explanation:

5(t-9.00) = 12(t-(9.00+3.00))

5·(t-9.00) = 12·(t-(9.00+3.00))

7t = 99

t = 99/7 = 14.14285714

t = 99/7 ≈ 14.142857
