You just have to divide the number of blocks walked by the number of hours
48 / 3 = 16 blocks per hour
Are those supposed to be comas or decimal points , if they’re comas then i think the scientific notation would be 1.222 x 10^8
First you substitute into the equation is/of=%/100. By that, I mean, 119/x=70/100. Cross multiply to get 119(100)=70x. Solve for x=170
Solve with one variable for both sides.
