With the sum of 99, we will get 50 pairs whole numbers. Why?
Let’s start with
0+ 99
1 + 98
2 + 97
3 + 96
4 + 95
5 + 94
6 + 93
7 + 92
8 + 91
9 + 90
10 + 89
………
……..
43 + 49
44 + 50
Therefore, if you’re going to count all pairs of whole number, you will get 50 pairs of whole number with the sum of 99.
Hope this helps!
Answer:
First find the circumference of both wheels
C = pi d
Large wheel = 3.14 * 60
= 188.4
Small wheel = 3.14 * 18
= 56.52
Divide them both with divide 600 by the circumference
Large wheel = 600/188.4 = 3.18 or <em>3 rotations</em>
Small wheel = 600/56.52 = 10.61 or <em>11 rotations</em>
<em>b. 2 large wheels. This is because you can cover more distance with large wheels that small wheels. Large wheels are also worth the energy.</em>
