NONO NONO's answer to shell's Primary 6 Maths Speed Singapore question.
Sorry, typo it is h =48,000/3,000 (not 30,000) but the rest is fine.
thank you
the 30cm information in the beginning doesn't really affect the result. you are welcome!
ok yes i saw the typo but the answer is fine so i ignored it but thanks anyways!
