Can some one help me in this :)

16m/s

Step-by-step explanation:

distance travelled from L to M = 6 x 10 = 60m

distance travelled from M to N = 160 - 60 = 100m

time taken to travel from M to N = 100/25 = 4 seconds

average speed = total distance / total time = 160m / (6 + 4) seconds = 16m/s

hope that helps!

this is a question on speed, distance and time. I have a formula for it up in my insta page (learntionary) if you need it :)

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
