Question

if 25 cm long candle burn for 45 minutes how long will another candle of the same material and thickness but 5 cm longer than the previous one,burn​

Answer 1

Answer:

Previous length =25cm

Previous time taken for burning =45 minutes

New length = 5cm longer than previous length = 5+ 25= 30cm

Time taken for 25cm long candle= 45 minutes

Time taken for 1cm long candle = 45/25cm =1.8

Time taken for 30cm long candle = 30 × 1.8 = 54minutes
