At 10 57, Usha cycled from the salon towards the cinema while Esther cycled from the cinema towards the salon. At 11 12, the two cyclists passed each other. 13 minutes later, Usha reached cinema but Esther was 1080 m from the salon.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cinema and the salon in km.
(a)
From 10 57 to 11 12 = 15 min
Combined speed of the two cyclists
= 1080 ÷ (15 - 13)
= 540 m/min
(b)
Distance between the cinema and the salon
= 15 x 540
= 8100 m
1000 m = 1 km
8100 m = 8.1 km
Distance between the cinema and the salon = 8.1 km
Answer(s): (a) 540 m/min; (b) 8.1 km
