Question

Which activity includes a moment when both feet are off the ground?

walking

speed walking

running

walking and running

Answer 1

The activity that includes a moment when both feet are off the ground is **running**. While walking generally maintains at least one foot on the ground at all times, running has a phase where both feet are in the air simultaneously. Speed walking, like regular walking, does not have a moment when both feet leave the ground. Therefore, the correct answer is **running**.
