Question

At the end of a snow storm, Gavin saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 0.5 inches per hour

Answer 1

Answer: 20 hr

Explanation:

Given

The depth of accumulated snow is
`d=10\ in.`

Snow is melting at the rate of
`r=0.5\ \text{in. per hour}`

Time taken for complete melting of snow is

`\Rightarrow t=(d)/(r)\\\\\Rightarrow t=(10)/(0.5)=20\ hr`
