A baby saw a toy and scooted closer, moving 1 3 of a meter in 1 4 of a minute. How fast was the baby moving?

the baby is moving meter a minute

Step-by-step explanation:

The computation is shown below:

Hence, the baby is moving meter a minute

We just simply added the two above fractions so that the timing could come in a correct way

They are supplementary because angle 12 is congruent with angle 10 which is supplementary with angle 7 ( that means the measure of angle7+ the measure of angle 12 is 180 grades)
12 and 10 are congruent due to the fact that A and B are two parallel lines and D is a sequent (i don't know how to spell this word). i guess you get it
