We have to convert the distance of 0.25 kilometers into feet. First, we convert 0.25 kilometers into meters. Since 1 kilometer has 1000 meters, we multiply 0.25 km by 1000 m/km to get 250 m. Next, 1 foot has 0.3048 m, so we divide the 250 meters by 0.3048 m/ft to get the number of feet, which is 820.21 ft.
