At 13 58, Sarah cycled from the hospital towards the church while Lynn cycled from the church towards the hospital. At 14 15, the two cyclists passed each other. 15 minutes later, Sarah reached church but Lynn was 960 m from the hospital.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the church and the hospital in km.
(a)
From 13 58 to 14 15 = 17 min
Combined speed of the two cyclists
= 960 ÷ (17 - 15)
= 480 m/min
(b)
Distance between the church and the hospital
= 17 x 480
= 8160 m
1000 m = 1 km
8160 m = 8.16 km
Distance between the church and the hospital = 8.16 km
Answer(s): (a) 480 m/min; (b) 8.16 km
