At 12 51, Pamela cycled from the salon towards the hospital while Tina cycled from the hospital towards the salon. At 13 11, the two cyclists passed each other. 9 minutes later, Pamela reached hospital but Tina was 935 m from the salon.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the salon in km.
(a)
From 12 51 to 13 11 = 20 min
Combined speed of the two cyclists
= 935 ÷ (20 - 9)
= 85 m/min
(b)
Distance between the hospital and the salon
= 20 x 85
= 1700 m
1000 m = 1 km
1700 m = 1.7 km
Distance between the hospital and the salon = 1.7 km
Answer(s): (a) 85 m/min; (b) 1.7 km
