At 11 58, Opal cycled from the hospital towards the park while Hilda cycled from the park towards the hospital. At 12 18, the two cyclists passed each other. 15 minutes later, Opal reached park but Hilda was 925 m from the hospital.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the park and the hospital in km.
(a)
From 11 58 to 12 18 = 20 min
Combined speed of the two cyclists
= 925 ÷ (20 - 15)
= 185 m/min
(b)
Distance between the park and the hospital
= 20 x 185
= 3700 m
1000 m = 1 km
3700 m = 3.7 km
Distance between the park and the hospital = 3.7 km
Answer(s): (a) 185 m/min; (b) 3.7 km
