Answer 1

Question :

sarita walks 1/2 hour on the first day , 1/4 on the second day and follows the same partern . how long she will walk in four days .

To find :

The time taken for walking in four days

Solution :

Sarita walks 1/2 hours on the first day

On the second day she walks 1/4 hours.

So by following the pattern,

on the third day she will walk 1/8 hrs

So she would walk 1/16 hrs on the fourth day

Now,

The numbers are to be added to get the total time taken by her.

$\frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \frac{1}{16}$

$\frac{2}{4} + \frac{1}{4} + \frac{2}{16} + \frac{1}{16}$

$\frac{3}{4} + \frac{3}{16}$

$\frac{12}{16} + \frac{3}{16}$

$\frac{15}{16} \sf \: hrs$

So she will walk for 15/16 hrs Iin four days.
