Final answer:
To find Naureen's rate of walking in kilometers per hour, we need to convert the distance walked from kilometers and meters to just kilometers and the time from minutes to hours.
Step-by-step explanation:
To find Naureen's rate of walking in kilometers per hour, we need to convert the distance walked from kilometers and meters to just kilometers and the time from minutes to hours.
Naureen walked 2 km and 500 m in 50 minutes. To convert 500 m to kilometers, we divide it by 1000. So, 500 m = 0.5 km. Now, the total distance walked is 2 km + 0.5 km = 2.5 km.
Next, we need to convert the time from minutes to hours. Since there are 60 minutes in an hour, we divide 50 minutes by 60 to get the time in hours. So, 50 minutes = 50/60 = 5/6 hours.
To find the rate of walking, we divide the distance walked by the time taken: 2.5 km / 5/6 hours. When we divide a fraction by another fraction, we multiply the first fraction by the reciprocal of the second fraction. So, 2.5 km / 5/6 hours = 2.5 km * 6/5 hours = 15/5 =3 km/h.
Therefore, Naureen's rate of walking is 3 kilometers per hour.
Naureen walked 2 km and 500 m in 50 minutes. To find the rate of walking, we divide the distance walked by the time taken: 2.5 km / 5/6 hours. Therefore, Naureen's rate of walking is 3 kilometers per hour.
