The average wait time is simply the averages of all the wait times in a product category. For instance, a custom watch manufacturer might have a wait time that ranges from 5 days to 10 days for a model A watch depending on the options. The average wait time for the model A watch is 7.5 days.
To find the answer, first lets divide the width and length by the scale amount given, 2 cm.
Width: 4 cm / 2 cm = 2
Length: 6 cm / 2 cm = 3
After this, we multiply the result by the amount to scale up, in this case 4 feet.
Width: 2 * 4 = 8 feet
Length: 3 * 4 = 12 feet
Therefore the answer is the first option.
Multiply 1/5 and 1/4 so that everything has a common denominator of 200.
1/5*40/40 = 40/200
1/4*50/50 = 50/200
