Tourists

From the cottage started first group of tourists at 7:00 AM at speed 4 km/h. The second started after them 21 minutes later at speed 6 km/h. How long and how many kilometers from the cottage will catch the first group?

Correct answer:

t =  0.7 h
s =  4.2 km

Step-by-step explanation:

v1=4 km/h v2=6 km/h t2=21 min h=21:60  h=0.35 h  s1=s2=s  v1 (t+t2)=v2 t 4 (t+0.35)=6 t  2t=1.4  t=107=0.7=0.7 h
s=v2 t=6 0.7=4.2 km
