Students! Let's do an activity. In given triangle ABC If AB=4cm, AC= 6 cm and three

Parallel lines cut AB at points P, Q and R in such that AP=PQ=QR=RS and AC point at X, Y and Z

such that

AX=XY=YZ=ZC, If PX || BC then what will AP PB AX XC =-?

Gaurav: AP PB AX XC 1 3 But I think this is BPT. Please Explain it.

Answer 2

Answer:

s=v*t

In this case v=c=3*10^8m/s

And t=2.5=5/2 seconds

Therefore s= 3 * 10.10^7 x 5/2

                   = 7.5*10^8 m
