During curfew Mr and Mrs Langbauer like to go for a walk. Mr. Langbauer keeps track of their time and total distance walked. He knows for the first 11 minutes they walk at a constant rate of 1000 m per 10 minutes. Then heading to the horse barn they slow a little and walk 18 minutes at a rate of 80m per minute. Then on the way back they walked for 20 minutes at a rate of 120 meters per minute. They saw Ms. Newberry and stopped to chat (at a distance) for 5 minutes and then finished their walk by walking for 8 minutes at 100 meters per minute.
