At 11 57, Hilda cycled from the grocery store towards the cafe while Erika cycled from the cafe towards the grocery store. At 12 12, the two cyclists passed each other. 13 minutes later, Hilda reached cafe but Erika was 1148 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cafe and the grocery store in km.
(a)
From 11 57 to 12 12 = 15 min
Combined speed of the two cyclists
= 1148 ÷ (15 - 13)
= 574 m/min
(b)
Distance between the cafe and the grocery store
= 15 x 574
= 8610 m
1000 m = 1 km
8610 m = 8.61 km
Distance between the cafe and the grocery store = 8.61 km
Answer(s): (a) 574 m/min; (b) 8.61 km
