At 10 57, Emma cycled from the clinic towards the cafe while Shiyun cycled from the cafe towards the clinic. At 11 12, the two cyclists passed each other. 12 minutes later, Emma reached cafe but Shiyun was 1086 m from the clinic.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cafe and the clinic in km.
(a)
From 10 57 to 11 12 = 15 min
Combined speed of the two cyclists
= 1086 ÷ (15 - 12)
= 362 m/min
(b)
Distance between the cafe and the clinic
= 15 x 362
= 5430 m
1000 m = 1 km
5430 m = 5.43 km
Distance between the cafe and the clinic = 5.43 km
Answer(s): (a) 362 m/min; (b) 5.43 km
