Question

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

Answer 1

Let's Solve it!

first candle’s length=25cm,then length of second candle will be =25+5=30cm.

It can be answered by Ratio and Proportion.Like this:-

we have to take one of things in fractions and the things which are related to them in direct proportion (on the other side of ‘=’) in fraction.Let another time which is not given be x

=25/30=45/x

=x=(45/25)30

=x=54 .That is our Answer!!!

Answer 2

Step-by-step explanation:

length of the candle is directly proportion to the time

if 25cm candle burns in 45m

then 25+5=30cm candle burns in x

25/45=30/x

=5/9=30/x

=9×30/5=x

=9×6=x

=54=x

so 30cm candle burns in in 54m
