17.5 meters

Explanation:

When using constant velocity, we can use the equation d = vt, or
distance = velocity * time

So, since we know the time and velocity, we can plug those in to our equation to find the distance.

our velocity is 2.5 m/s
our time is 7 seconds
our distance is unknown.

this gives us d=(2.5ms)โ‹…(7s)

When we calculate (2.5โ‹…7) we get 19.84 as our distance.

To remember this with logic, instead of formula, you can think of it as:

If i am moving at a distance of 2.5 meters for every second I walk, and want to walk for 7 seconds, I will walk 2.5 meters seven times.

So, 2.5+2.5+2.5+2.5+2.5+2.5+2.5=2.5โ‹…7,or17.5 meters.
