The ratio of the length of candle A to the length of candle B at first will be 3 / 5.
A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Candle A and candle B were lit at the same time. candle a could last 3 hours and candle b could last 5 hours. after 1 hour, both candles were equal in length.
Then the ratio of the length of the candle A to the length of candle B at first will be
Let the length of candle A is x and the length of candle B be y.
The common speed will be S.
Then we have
Time = length / speed
For candle A, we have
Candle A = x / S = 3 ...1
For candle B, we have
Candle B = y / S = 5 ...2
From equations 1 and 2, we have
x / 3 = y / 5
x / y = 3 / 5
