At 10 57, Kimberly cycled from the hospital towards the farm while Diana cycled from the farm towards the hospital. At 11 12, the two cyclists passed each other. 7 minutes later, Kimberly reached farm but Diana was 1168 m from the hospital.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the farm and the hospital in km.
(a)
From 10 57 to 11 12 = 15 min
Combined speed of the two cyclists
= 1168 ÷ (15 - 7)
= 146 m/min
(b)
Distance between the farm and the hospital
= 15 x 146
= 2190 m
1000 m = 1 km
2190 m = 2.19 km
Distance between the farm and the hospital = 2.19 km
Answer(s): (a) 146 m/min; (b) 2.19 km
