Answer

Answer:

B. $3\leq t\leq4$

Explanation:

Step1: Recall speed - slope relation

Speed is related to the slope of the height - time graph.

Step2: Analyze slope of intervals

The steeper the graph, the greater the speed.

Step3: Compare intervals

The interval $3\leq t\leq4$ has the steepest part of the graph.
