A road is 53 km 500 m long. Out of this, 15 km 800 m is closed for repairing. How much of the road is open to traffic?
53 km, 500 m = 52 km, 1500 m
52 km, 1500 m - 15 km, 800 m = ?
29km700m
To find out how much of the road is open to traffic, we need to subtract the length of the closed portion from the total length of the road.
The total length of the road is 53 km 500 m. We can convert this to a consistent unit, such as meters. Since 1 kilometer is equal to 1000 meters, we have:
Total length of road = 53 km + 500 m
= (53 * 1000 m) + 500 m
= 53,500 m
Similarly, the closed portion of the road is 15 km 800 m. Converting this to meters, we have:
Length of closed portion = 15 km + 800 m
= (15 * 1000 m) + 800 m
= 15,800 m
Now, to find the length of the road open to traffic, we subtract the length of the closed portion from the total length of the road:
Length of open road = Total length of road - Length of closed portion
= 53,500 m - 15,800 m
= 37,700 m
Therefore, the open portion of the road is 37,700 meters long.
