Question

I need the answer within a day. URGENT 

Answer 1

 X     =  12

100%    40

 

1. cross multiply, so:

    X x 40 = 40X and

   12 x 100 = 1200

 

2. then set equal, so:

      40X = 1200

 

3. solve for X, so: divide both sides by 40

       X = 30 

 

4. answer is 30% of his time is spent walking

 

 

OR

 

1. percentage (%) = 12min / 40 total min = 0.3 x 100% = 30%
