Answer:
From the figure above (not drawn to scale)
The total distance covered by Puja = AB + BC + CD + DA
= 20 km + 10 km + 10 m + 15 km
Adding or subtracting quantities with units is allowed only if the quantities have the same units.
Here to get the total distance in km, we should convert the distance given in meters to kilometers.
∵
1 m =
1
1000
km
∴
10 m =
10
1000
km = 0.01 km
Therefore, total distance covered by Puja = 20 + 10 + 0.01 + 15 = 45.01 km
