At 11 57, Jaslyn cycled from the grocery store towards the bakery while Natalie cycled from the bakery towards the grocery store. At 12 12, the two cyclists passed each other. 7 minutes later, Jaslyn reached bakery but Natalie was 960 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bakery and the grocery store in km.
(a)
From 11 57 to 12 12 = 15 min
Combined speed of the two cyclists
= 960 ÷ (15 - 7)
= 120 m/min
(b)
Distance between the bakery and the grocery store
= 15 x 120
= 1800 m
1000 m = 1 km
1800 m = 1.8 km
Distance between the bakery and the grocery store = 1.8 km
Answer(s): (a) 120 m/min; (b) 1.8 km
