Answer:   d = 3t

======================================================

Explanation:

I'm using the formula

d = rt

where

  • d = distance
  • r = rate, aka speed
  • t = time

Afterward, I replaced r with 3 to represent the 3 km/hr speed.

So that's how we go from d = rt to d = 3t

If for example, they traveled for t = 2 hours, then d = 3t = 3*2 = 6 km is the distance they walk.

Answer:

d = (3 km/hr)t

Step-by-step explanation:

Recall that distance = rate times time.

Here, distance = (3 km/hr)(time), or d = (3 km/hr)t, where t:  number of hours
