At 10 59, Barbara cycled from the hypermart towards the hospital while Kimberly cycled from the hospital towards the hypermart. At 11 17, the two cyclists passed each other. 15 minutes later, Barbara reached hospital but Kimberly was 1035 m from the hypermart.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the hypermart in km.
(a)
From 10 59 to 11 17 = 18 min
Combined speed of the two cyclists
= 1035 ÷ (18 - 15)
= 345 m/min
(b)
Distance between the hospital and the hypermart
= 18 x 345
= 6210 m
1000 m = 1 km
6210 m = 6.21 km
Distance between the hospital and the hypermart = 6.21 km
Answer(s): (a) 345 m/min; (b) 6.21 km
