holes are drilled 35.7mm apart in a metal plate. if a row of 26 holes is drilled, determine the distance in centimeters (cm) between the centres of the first and last holes. (answer is 89.25) can you show the method in working this out?
If you drill TWO holes there is ONE space between
If you drill THREE holes there is TWO spaces between
...
If you drill 26 holes there is 25 spaces between 25 x 35.7mm = 892.5 mm = 89.25 cm
