Question

A squirrel runs across a road in 3 seconds. The road was more than 34 feet wide. Which inequality can be used to determine the squirrel’s speed?

3r is greater than 34
3r is less than 34
r/3 is greater than 34
r/3 is less than 34

What is the solution to the inequality? Round to the nearest tenth, if necessary.
r less than 11.3
r greater than 11.3
r less than 102
r greater than 102

How can you interpret the solution?
The squirrel can run at least 11.3
The squirrel can run faster than 11.3
The squirrel can run no faster than 102
The squirrel can run slower than 102

Answer 1

Explanation:

squirrel speed (r) x seconds (3) has to be more than 34 feet

3r is greater than 34

r is greater than 11.3

34 / 3 = 11.333

11.3 (squirrels speed) x 3 (seconds) = 33.9 feet

the squirrel can run faster than 11.3

Answer 2

A). Option A

B). Option B

C). Option B

Explanation:

A). A squirrel runs across a road in 3 seconds.

Width of the road is more than 34 feet.

We have to calculate the squirrel speed.

Speed =
`\frac{\text{Distance}}{\text{Time}}`

=
`(34)/(3)`

Since distance is more that 34 so the speed will be more than
`(34)/(3)`

This is because Speed ∝ Distance.

Let r is the speed of squirrel.

r >
`(34)/(3)`

3r > 34

Option A is the correct option.

B). Inequality is 3r > 34

r >
`(34)/(3)`

r > 11.3

Option B is the answer.

C). The squirrel can run at faster than 11.3 feet per second.

Option B.
