At 11 58, Sarah cycled from the mosque towards the hospital while Lucy cycled from the hospital towards the mosque. At 12 18, the two cyclists passed each other. 11 minutes later, Sarah reached hospital but Lucy was 1017 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the mosque in km.
(a)
From 11 58 to 12 18 = 20 min
Combined speed of the two cyclists
= 1017 ÷ (20 - 11)
= 113 m/min
(b)
Distance between the hospital and the mosque
= 20 x 113
= 2260 m
1000 m = 1 km
2260 m = 2.26 km
Distance between the hospital and the mosque = 2.26 km
Answer(s): (a) 113 m/min; (b) 2.26 km
