At 13 54, Hazel cycled from the grocery store towards the library while Emily cycled from the library towards the grocery store. At 14 12, the two cyclists passed each other. 14 minutes later, Hazel reached library but Emily was 1060 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the library and the grocery store in km.
(a)
From 13 54 to 14 12 = 18 min
Combined speed of the two cyclists
= 1060 ÷ (18 - 14)
= 265 m/min
(b)
Distance between the library and the grocery store
= 18 x 265
= 4770 m
1000 m = 1 km
4770 m = 4.77 km
Distance between the library and the grocery store = 4.77 km
Answer(s): (a) 265 m/min; (b) 4.77 km
