Answer:

Before we begin, first convert the minutes unit to seconds to match the unit for speed. Since there are 60 seconds in a minute, and there are 3 minutes, 3*60 = 180 seconds. Using the formula s = d/t, we can manipulate this formula to solve for d, the distance. So we isolate the d variable, to get d = st, and we can substitute the values of s and t into this formula. Now we have d = 4m/s*180s. Now we solve this to get d = 720m. Now we can convert meters to miles, to get approximately 0.45 miles.
