Janka Katka meeting

Jane and Kate live in villages 16 km away. They agreed to meet precisely halfway. Jane was driving at a speed of 4 km/h. Kate came out 30 minutes later. At what speed must Kate drive to fulfill the agreement?

Final Answer:

v2 =  5.3333 km/h

Step-by-step explanation:

s=16 km v1=4 km/h t0=30 min h=30:60  h=0.5 h  v1 t = s/2 t=2 v1s=2 416=2 h  v2 (tt0)=s/2  v2=2 (tt0)s=2 (20.5)16=5.3333 km/h
