At 12 59, Lynn cycled from the hospital towards the library while Zoe cycled from the library towards the hospital. At 13 13, the two cyclists passed each other. 7 minutes later, Lynn reached library but Zoe was 945 m from the hospital.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the library and the hospital in km.
(a)
From 12 59 to 13 13 = 14 min
Combined speed of the two cyclists
= 945 ÷ (14 - 7)
= 135 m/min
(b)
Distance between the library and the hospital
= 14 x 135
= 1890 m
1000 m = 1 km
1890 m = 1.89 km
Distance between the library and the hospital = 1.89 km
Answer(s): (a) 135 m/min; (b) 1.89 km
