Question

Bags are filled with bird food at a rate of 420 grams per second.
How many 20 kg bags can be completely filled in 4 hours?​

Answer 1

Answer:

302 bags

Step-by-step explanation:

No of seconds in 4 hours = 4 X 60 X 60

                                          = 14400 s

if it fills 420g in 1 second.

So, the amount of bird food filled in 14400s = 14400 X 420

                                                                        =  6048000 g

                                                                        =   6048 kg

20kg can filled in 1 bag.

Therefore, no of bags that can be completely filled = 6048/20

                                                                                     = 302.4

                                                                                     = 302 bags

                                                                                     

Answer 2

Answer:

302 bags

Step-by-step explanation:

420g = 420/1000kg

= 0.42 kg

4 hours = 60 x 4 min

=240 min

=240 x 60 sec

=14400 sec

In 1 second 0.42 kg bird food is released

So in 14400 second 0.42 x 14400 bird food is released

= 0.42 x 14400

= 6048 kg of bird food

Therefore, no of 20kg bags is 6048/20

= 302.4 bags

302 bags will be filled
