At 12 59, Shiyun cycled from the bistro towards the hospital while Elyse cycled from the hospital towards the bistro. At 13 17, the two cyclists passed each other. 15 minutes later, Shiyun reached hospital but Elyse was 930 m from the bistro.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the bistro in km.
(a)
From 12 59 to 13 17 = 18 min
Combined speed of the two cyclists
= 930 ÷ (18 - 15)
= 310 m/min
(b)
Distance between the hospital and the bistro
= 18 x 310
= 5580 m
1000 m = 1 km
5580 m = 5.58 km
Distance between the hospital and the bistro = 5.58 km
Answer(s): (a) 310 m/min; (b) 5.58 km
