After a winter storm, the depth of the snow on cherry street was 10 cm. but then, the snow started melting at a rate of 1/3 cm per hour. what was the depth of the snow on cherry street after 3 hours?

In the beginnig, the depth of the snow on Cherry Street was 10cm .

And it started melting at a rate of 1/3 cm per hour.

It means after 1 hour, the height is 10-(1/3) , after two hours the height is 10-(2/3) . So after three hours, the depth of the snow on Cherry Street will be

Therefore the answer is 9 cm .

The depth of the snow on Cherry Street after 3 hours will be 9 cm.

Step-by-step explanation:

After a winter storm, the depth of the snow on Cherry Street was  10 cm.

The snow started melting at a rate of 1/3 cm per hour.

So, after 3 hours the snow meted = cm

Hence, the depth of the snow on Cherry Street after 3 hours will be = cm

The depth of the snow on Cherry Street after 3 hours will be 9 cm.

so, converting firstly the mixed fractions to improper fractions and then "adding".
