At 13 57, Jane cycled from the grocery store towards the museum while Mary cycled from the museum towards the grocery store. At 14 17, the two cyclists passed each other. 7 minutes later, Jane reached museum but Mary was 1105 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the museum and the grocery store in km.
(a)
From 13 57 to 14 17 = 20 min
Combined speed of the two cyclists
= 1105 ÷ (20 - 7)
= 85 m/min
(b)
Distance between the museum and the grocery store
= 20 x 85
= 1700 m
1000 m = 1 km
1700 m = 1.7 km
Distance between the museum and the grocery store = 1.7 km
Answer(s): (a) 85 m/min; (b) 1.7 km
