Answer 1

Answer:

135

Step-by-step explanation:

  1 Hour = 60 Minutes

∴ 3 Hours = ( 60 × 3 ) Minutes

                 = 180 Minutes

By Dora,

  In 4 minutes the number of toys is built is 3

∴ In 1 minute the number of toys is built is  $\frac{3}{4}$

∴ In 180 minutes the number of toys is built is $\frac{3*180}{4}$

                                                                           = 135

Well, Dora would build 135 toys completely within 3 hours. (Ans)

Hope you got your needed answer...

Answer 2

Answer:

Dora will build 135 toys in 3 hours

Step-by-step explanation:

We know that,

Dora built 3 toys in 4 minutes, thus it is proportional

Now,

Here, she finishes the work in minutes, hence, we must convert hours into mins as well.

1 hour = 60 mins.

3 hours = 3 × 60 mins.

3 hours = 180 mins.

Thus,

Let here build x toys,

Thus, since they are proportional,

3/4 = x/180

Cross multiplying we get,

4 × x = 3 × 180

4x = 540

x = 540/4

x = 135

Hence,

Dora will build 135 toys in 3 hours

Hope it helped and believing you understood it........All the best
