Question

Rehana works 2*1/2 hours each day on her embroidery. She completes the work in 7 days. How many hours did she take to complete her work?

Answer 1

per day hrs.=2
$\frac{1}{2}$
=5/2hrs.
and total no. of days=7
so total no. of hrs.=35/2

Answer 2

Answer:

17.5 hours.

Step-by-step explanation:

Rehana works 2.5 hours every day.

So, in 1 day she works for 2.5 hours.

Now, she completes work within 7 days.

So, we can use the unitary method to get the number of hours she worked to complete the work.

Therefore, the work takes (7 times of 2.5 hours)= 7×2.5 =17.5 hours to complete the work.

Hence, she takes 17.5 hours to complete her work. (Answer)
