Play an AI-generated podcast conversation about this lesson

What is the formula to calculate speed?

Time + Distance

Time / Distance

Distance / Time (correct)

Distance x Time

If Clara took 200 seconds to run 800 meters instead of 260 seconds, what impact would it have on her speed?

Her speed would decrease

Her speed would become zero

Her speed would remain the same

Her speed would increase (correct)
