At 8 o'clock, Pepa went from Hůrka to Lhotka at a speed of 3 km/h, and at 9 o'clock, Tonda went from Lhotka to Hůrka at a rate of 5 km/h. How far apart are the two villages if Pepa and Tonda meet at 9:30 am?

Correct answer:

s =  7 km

Step-by-step explanation:

v1=3 km/h t1=8.00 h t2=9.00 h v2=5 km/h  t=9+30/60=219=9.5 h  s=v1 (tt1)+v2 (tt2)=3 (9.58)+5 (9.59)=7 km
