At 11 59, Natalie cycled from the school towards the grocery store while Elyse cycled from the grocery store towards the school. At 12 13, the two cyclists passed each other. 8 minutes later, Natalie reached grocery store but Elyse was 1080 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the school in km.
(a)
From 11 59 to 12 13 = 14 min
Combined speed of the two cyclists
= 1080 ÷ (14 - 8)
= 180 m/min
(b)
Distance between the grocery store and the school
= 14 x 180
= 2520 m
1000 m = 1 km
2520 m = 2.52 km
Distance between the grocery store and the school = 2.52 km
Answer(s): (a) 180 m/min; (b) 2.52 km
