At 11 54, Raeann cycled from the hypermart towards the hospital while Nicole cycled from the hospital towards the hypermart. At 12 13, the two cyclists passed each other. 15 minutes later, Raeann reached hospital but Nicole was 920 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the hypermart in km.
(a)
From 11 54 to 12 13 = 19 min
Combined speed of the two cyclists
= 920 ÷ (19 - 15)
= 230 m/min
(b)
Distance between the hospital and the hypermart
= 19 x 230
= 4370 m
1000 m = 1 km
4370 m = 4.37 km
Distance between the hospital and the hypermart = 4.37 km
Answer(s): (a) 230 m/min; (b) 4.37 km
