At 11 57, Shannon cycled from the grocery store towards the boutique while Tina cycled from the boutique towards the grocery store. At 12 12, the two cyclists passed each other. 10 minutes later, Shannon reached boutique but Tina was 1130 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the boutique and the grocery store in km.
(a)
From 11 57 to 12 12 = 15 min
Combined speed of the two cyclists
= 1130 ÷ (15 - 10)
= 226 m/min
(b)
Distance between the boutique and the grocery store
= 15 x 226
= 3390 m
1000 m = 1 km
3390 m = 3.39 km
Distance between the boutique and the grocery store = 3.39 km
Answer(s): (a) 226 m/min; (b) 3.39 km
