The tourist rode a bicycle for 1 hour at a speed of 10 km / h, then rested for 0.5 hours, then walked 7.5 km in 1.5 hours. Find the average speed of the tourist along the way.
To determine the average speed of a tourist, the total distance must be divided by the total time. The first part of the distance the tourist rode on a bicycle, in 1 hour he covered 1 hour X 10 km / h = 10 km. The total distance will be 10 km + 7.5 km = 17.5 km. The total time is 1 hour + 0.5 hours + 1.5 hours = 3 hours. We find the average speed of a tourist: 17.5 km / 3 hours = 5.8 km / h.
The answer is rounded to the nearest tenth.
