The diagram shows a 5m wide section of road that has a uniform gradient. The shaded area represents level ground. Two cyclists, Delyth and Ioan, approach this section of road. Delyth cycles straight up the middle of the road as shown by the arrow. Ioan thinks this section of road is too steep to cycle straight up, so he decides to cycle from A to B in a straight line. It has been calculated that the distance between A and B is 9.5 m. Show that Ioan’s route up this section of road is less steep than Delyth’s route.
