Car A and car B take part in a race around a circular track. One lap of the track measures 7.6 km.

Car A takes 2 minutes and 40 seconds to complete each lap of the track.

Car B takes 2 minutes and 25 seconds to complete each lap of the track.

Both cars travel at a constant speed.

(a) Calculate the speed of car A.

Give your answer in kilometres per hour.

km/h

(b) Both cars start the race from the same position, S, at the same time.

(i) Find the time taken when both car A and car B are next at position S at the same time.

Give your answer in minutes and seconds.

(ii) Find the distance that car A has travelled at this time.
