On one side of a 1.01 km long road, 101 plants are planted at equal distance from each other. What is the total distance between 5 consecutive plants?
40 m
40.4 m
50 m
50.5 m
Solution
The road is 1010 m long with 101 plants, giving 100 equal gaps, so each gap = 1010/100 = 10.1 m. Between 5 consecutive plants there are 4 gaps, so the distance = $4 \times 10.1 = 40.4$ m.
