Answer 1

Answer:

22.5km

Step-by-step explanation:

Starting with same point,let a car travelling with 39km/hr=(39/60)km/min

so a travells (39*15/60)=(39/4)km in 15 min

another car b travels with 51km/hr=(51/60)km/min

so car b travels (51*15/60)=(51/4)km in 15 min

They travel to opposite side..So distance between them will be added..

so distance between them=(39/4+51/4)km=(90/4)km=22.5km

Hope this helps))
