Important please help physics question

A lens has a focal length of approximately 2.3×10^4 micrometres. The tip of a pencil is placed 553mm from the lens. Calculate image distance in metres
I got 0.022 m but answer is 0.024m?
1/v = 1/f (-1/u), so 1/0.023 - 1/553x10^-3 is 41.6 which is the value for 1/v, so v is 1/41.6 which is 0.024

What is 1/v?

it’s 1 divided by the image distance, v is the symbol used for the image distance :smile:
