Figure 1.7 shows the result of unacceptable error in the stopping position of a train. (a) If a train travels 890 km from Berlin to Paris and then overshoots the end of the track by 10 m, what is the percent error in the total distance covered? (b) Is it correct to write the total distance covered by the train as 890,010 m? Explain.

Solution 13E Step 1 : Distance travelled by the train from Berlin to Paris d = 890 km Distance overshoot due to track d e 10 m Converting this to KM 1km 10m × 100m = 0.01 km Hence we the get total distance travelled as 890 km + 0.010km = 890.01 km
