Question

There are three trucks A, B, C. A loads 10 kg/min. B loads 13 1/3 kg/min. C unloads 5 kg/min. If three simultaneously works then what is the time taken to load 2.4 tones?

Answer 1

Dear student:

A loads 10 kg/min.

B loads 13 1/3 kg/min=40/3kg/min.

C unloads 5 kg/min.

A,B and C work simultaneously.

A,B and C loads simultaneously=40/3+10-5

                                                     =55/3 kg/min

So,1 kg loading = 3/55 minute.

For 2.4 tones=?

We konw, 1 tones=1000kg

So, 2.4 tones 2.4*1000kg

Time taken by A,B and C is = 2.4*1000*3/55

                                             =131 minute.

Hope it helps

Thanks
