Answer:
9 cm.
Step-by-step explanation:
Let x be the number of hours.
We have been given that after a winter storm, the depth of the snow on cherry street was 10 cm. Then, the snow started melting at a rate of , so the snow melted in x hours will be .
Since initially there was 10 cm of snow, so the depth of snow after x hours will be:

0.89 hours
Step-by-step explanation:
Micheal and his sister Mel share the task of mowing the grass in their yard.
Micheal mows 1/3 of the yard
= 1-1/3
= 2/3
Mel mows the rest portion
Mel can now mow 1/3 of the yard in one hour
Therefore the time taken by Mel to finish mowing the yard can be calculated as follows
= 2/3 ÷ 3/4
= 2/3 × 4/3
= 8/9
= 0.89 hours
Hence it will take Mel 0.89 hours to finish mowing the yard
