A pin, 14 mm long, is made of wire. Determine how many whole pins could be made from 1 km of wire.
Question
A pin, 14 mm long, is made of wire.
Determine how many whole pins could be made from 1 km of wire.
Solution
- First, we need to convert the length of the wire from kilometers to millimeters because the length of the pin is given in millimeters. We know that 1 kilometer is equal to 1,000,000 millimeters.
- So, 1 km of wire is 1,000,000 mm.
- Now, we divide the total length of the wire by the length of one pin to find out how many pins can be made.
- So, 1,000,000 mm / 14 mm = 71,428.57 pins.
- However, since we can't have a fraction of a pin, we round down to the nearest whole number.
- Therefore, 71,428 whole pins can be made from 1 km of wire.
