Consider the following frequency distributio Class Interval 100-under 200 Frequency 25

1. An ambulance is called to the scene of an accident 4 kilometres away from the ambulance station. The distance, in kilometres, that the ambulance has traveled to the scene, t seconds after leaving the station, is given in the following table: Time (s) Distance (km) 0 0.5 a. Over which 30-second interval(s) did the ambulance travel the fastest? b. Over which 30-second interval(s) did the ambulance travel the slowest? c. Determine the average speed of the ambulance, in kilometres per hour, over its entire trip to the accident. 0 30 60 1.5 90 1.75 120 2.75 150 3.25 180 4.0
