In this case, the number that we are "comparing" to 100 is 52, so we must first normalize the number by dividing it by 100. The operation we have to solve is this:
52
100
=
52
÷
100
=
0.52
Step 2: Multiply 0.52 by 72 to get the solution
Now that we have our normalized number, 0.52, we just have to multiply it by 72 to get our final answer. The forumla for this is obviously quite simple:
To find the average speed of the jet, we divide 4000 by 5. When we do so, we get 800. Therefore, the average speed of the jet was 800 kilometers per hour. Hope this helped!
