Which situation could be represented by 1.25 x 6 = 7.5?

-it took calvin 1.25 hours to run 6 miles. he ran 7.5 miles per hour.

-sara read for 1.25 hours each day for 6 days. she read for a total of 7.5 hours.

-matthew addressed 1.25 envelopes in 6 minutes. he addressed 7.5 envelopes per minute.

-it took beth 1.25 minutes to paint 6 feet of board. she painted a total of 7.5 feet of the board.

The correct answer is the 1st option because the others don't make sense at all.

HOPE THIS HELPS!

HAVE A GR8 DAY! ;-)

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.
