Show work

Answer 1

As 1 mile = 1609 m and 1 km = 1000 m, then a person walks a distance (km)= 1mile*1609m/mile /1000 m /km= 1.609 km

As 1 hour is 60 minutes, then the time (hours) a person walks 1.609 km is t= 29 min / 60 min/hour = 0.483 hours

Speed= distance/time = 1.609 km /0.483 h = 3.331 km/hour

Answer: 3.331 km/hour
