Logan wants to determine the distance across the river from points B to C. If she is able to determine the measures given on the map using surveyors’ tools, what is the distance between points B and C? Round the answer to the nearest tenth of a foot
We have no access to your map.
To determine the distance between points B and C on a map, you can follow these steps:
1. Look for a scale on the map: Examine the map to find a scale or legend that provides a conversion ratio between the measurements on the map and the actual distances on the ground. This scale is usually given in terms of a certain distance on the ground corresponding to a specific length on the map.
2. Measure the distance between points B and C on the map: Use a ruler or other measuring tool to measure the distance between points B and C on the map in inches or centimeters. Make sure to align the ruler with the straight line connecting the two points.
3. Convert the measured distance to the actual distance: Apply the conversion ratio from the map's scale to convert the measured distance on the map to the corresponding actual distance. Multiply the measured distance by the conversion ratio to obtain the actual distance.
For instance, let's say the scale on the map indicates that 1 inch on the map corresponds to 50 feet in reality. If you measure the distance between points B and C on the map to be 3 inches, you would multiply 3 inches by 50 feet/inch to get the actual distance in feet.
Once you have determined the actual distance, round it to the nearest tenth of a foot as specified in the question to find the distance between points B and C.
