Answer: 10cm

Explanation:

From the question, we are informed that Boris has a tall candle which burns down 1 cm are in 1/5 hour.

The equation that can be used to calculate the number of centimeters of the candle that will burn down in 2 hours will then be represented by x. This will then be:

1cm/x = 1/5hour / 2 hours

Cross multiply

1/5 × x = 2 × 1

1/5x = 2

x = 2 ÷ 1/5

x = 2 × 5.

x = 10

The candle will burn 10cm in 2 hours.
