Problem

A scooter covers 300 m300\,\text{m} in 25 s25\,\text{s}, then remains at rest for 5 s5\,\text{s}, and finally covers 200 m200\,\text{m} in 20 s20\,\text{s}. What is the scooter’s average speed for the entire interval? (a) 11 m/s11\,\text{m/s} (b) 9 m/s9\,\text{m/s} (c) 10 m/s10\,\text{m/s} (d) 7.3 m/s7.3\,\text{m/s}
