Answer 2

Given:

Given that, Siya runs 6 kilometers every Sunday, Wednesday and Friday

Also, a month has 5 Sundays, 4 Wednesdays and 4 Fridays.

To find:

We need to find the number of kilometers she will run in a month.

Solution:

According to the question, she runs 6 kilometers every Sunday, Wednesday and Friday.

So, she will run $6\times5$ kilometers in 5 Sundays.

Similarly, she will run $6\times4$ kilometers in 4 Wednesdays.

Similarly, she will run $6\times4$ kilometers in 4 Fridays.

So, total number of kilometers $=6\times5+6\times4+6\times4$

                                                     $=30+24+24$

                                                     $=78$ kilometers

Therefore, Siya will run 78 kilometers in a month.
