There are 4 colors, White ,Green , Red and Orange. And there is a spinner which has 4 sections.
To see how many there are visually you could write out the outcomes.
-White and section 1
-White and Section 2
-White and Section 3
-White and Section 4
-Green and Section 1
-Green and section 2
-Green and Section 3
-Green and Section 4
-Red and Section 1
Red and Section 2
Red and Section 3
Red and Section 4
Orange and Section 1
Orange and Section 2
Orange and Section 3
Orange and Section 4
When you count them up it equals 16 outcomes.
FAST WAY: just multiply the colors and spinner sections, which is also 16.
Let's say the diameter of the larger gear is "x".
the small one has a diameter of 16cm, we know that, this is 2.5 more than (1/4)x.
You'll need to convert both speeds into yards per minute.
12 mph = 12 mph 1760 yd 60 min
---------- * ------------ * ----------
1 mile 1 hr
Note that "miles" cancels. So does "hours." Finish this work.
Then convert 4.4 ft/sec into yards per minute.
Then, finally, compare your two rates via subtraction of the smaller from the larger.
