Kilometers 30021

The first group of tourists left the hut at 8:00 AM at a speed of 4 km/h. The second group of tourists followed them half an hour later at a speed of 6 km/h. How long and how many kilometers from the cottage will it catch up with the first group?

Correct answer:

t =  1 h
s =  6 km

Step-by-step explanation:

v1=4 km/h v2=6 km/h  s=v1 (t+1/2) s=v2 t s=4 (t+1/2) s=6 t  2s8t=4 s6t=0  Row221 Row1Row2 2s8t=4 2t=2  t=22=1 s=24+8t=24+8 1=6  s=6 t=1=1 h
