At 10 57, Olivia cycled from the grocery store towards the clinic while Tiffany cycled from the clinic towards the grocery store. At 11 17, the two cyclists passed each other. 7 minutes later, Olivia reached clinic but Tiffany was 910 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the clinic and the grocery store in km.
(a)
From 10 57 to 11 17 = 20 min
Combined speed of the two cyclists
= 910 ÷ (20 - 7)
= 70 m/min
(b)
Distance between the clinic and the grocery store
= 20 x 70
= 1400 m
1000 m = 1 km
1400 m = 1.4 km
Distance between the clinic and the grocery store = 1.4 km
Answer(s): (a) 70 m/min; (b) 1.4 km
