At 12 57, Kimberly cycled from the hypermart towards the park while Hazel cycled from the park towards the hypermart. At 13 12, the two cyclists passed each other. 13 minutes later, Kimberly reached park but Hazel was 1100 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the park and the hypermart in km.
(a)
From 12 57 to 13 12 = 15 min
Combined speed of the two cyclists
= 1100 ÷ (15 - 13)
= 550 m/min
(b)
Distance between the park and the hypermart
= 15 x 550
= 8250 m
1000 m = 1 km
8250 m = 8.25 km
Distance between the park and the hypermart = 8.25 km
Answer(s): (a) 550 m/min; (b) 8.25 km
