1/32 inches per day * 1day/ 24hours * 1hour/ 60minutes * 1minute /60seconds * 0.0254meter / 1inch * 1 000 000 000 nanometers/ 1meter= 9.19nanometers per second
Why is this it is because we are given that 1/32 inches grow per day so the need fisrt it transform day into hours, hours into minutes and minutes into seconds to get the growth in inches per second. Then we need to find it in nanometers so we transform inches into meter and meters into nanometers...Hoped it helped...
