At 12 57, Gillian cycled from the park towards the hospital while Shannon cycled from the hospital towards the park. At 13 14, the two cyclists passed each other. 7 minutes later, Gillian reached hospital but Shannon was 1100 m from the park.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the park in km.
(a)
From 12 57 to 13 14 = 17 min
Combined speed of the two cyclists
= 1100 ÷ (17 - 7)
= 110 m/min
(b)
Distance between the hospital and the park
= 17 x 110
= 1870 m
1000 m = 1 km
1870 m = 1.87 km
Distance between the hospital and the park = 1.87 km
Answer(s): (a) 110 m/min; (b) 1.87 km
