Explanation

Choice B is correct. It's given that Ty plans to walk at an average speed of $4$ kilometers per hour. The number of kilometers Ty will walk is determined by the expression $4 s$ , where $s$ is the number of hours Ty walks. The given goal of at least $24$ kilometers means that the inequality $4 s greater than or equals 24$ represents the situation. Dividing both sides of this inequality by $4$ gives $s greater than or equals 6$ , which corresponds to a minimum of $6$ hours Ty must walk.

Choice A is incorrect and may result from conceptual or calculation errors.

Choice C is incorrect and may result from conceptual or calculation errors.

Choice D is incorrect and may result from conceptual or calculation errors.
