At 12 55, Hilda cycled from the cinema towards the school while Linda cycled from the school towards the cinema. At 13 13, the two cyclists passed each other. 11 minutes later, Hilda reached school but Linda was 980 m from the cinema.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the school and the cinema in km.
(a)
From 12 55 to 13 13 = 18 min
Combined speed of the two cyclists
= 980 ÷ (18 - 11)
= 140 m/min
(b)
Distance between the school and the cinema
= 18 x 140
= 2520 m
1000 m = 1 km
2520 m = 2.52 km
Distance between the school and the cinema = 2.52 km
Answer(s): (a) 140 m/min; (b) 2.52 km
