At 11 55, Lynn cycled from the hospital towards the school while Diana cycled from the school towards the hospital. At 12 14, the two cyclists passed each other. 9 minutes later, Lynn reached school but Diana was 900 m from the hospital.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the school and the hospital in km.
(a)
From 11 55 to 12 14 = 19 min
Combined speed of the two cyclists
= 900 ÷ (19 - 9)
= 90 m/min
(b)
Distance between the school and the hospital
= 19 x 90
= 1710 m
1000 m = 1 km
1710 m = 1.71 km
Distance between the school and the hospital = 1.71 km
Answer(s): (a) 90 m/min; (b) 1.71 km
