At 12 57, Lynn cycled from the mosque towards the hospital while Sarah cycled from the hospital towards the mosque. At 13 12, the two cyclists passed each other. 9 minutes later, Lynn reached hospital but Sarah was 1044 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 12 57 to 13 12 = 15 min
Combined speed of the two cyclists
= 1044 ÷ (15 - 9)
= 174 m/min
(b)
Distance between the hospital and the mosque
= 15 x 174
= 2610 m
1000 m = 1 km
2610 m = 2.61 km
Distance between the hospital and the mosque = 2.61 km
Answer(s): (a) 174 m/min; (b) 2.61 km
