Step-by-step explanation:
we know,
d=s×t so,let's do it.
d1=100×2=200., d2=150×3=450.
total d=d1+d2=(200+450)=650.
total time taken=(2+3)=5h.
therefore,average speed=total distance/total time.
=260/5=52km/hr.
plz it as brainliest and follow me

Answer:
distance between trains = 200
speed of train from p = 100kmph
speed of train from q = 150kmph
time taken to meet =
200
100
+
150
=
4
5
in that time the distance travelled by p is
100
×
4
5
i.e., 80km
so both trains meet at 80km from P
