At 11 57, Kylie cycled from the school towards the hypermart while Natalie cycled from the hypermart towards the school. At 12 17, the two cyclists passed each other. 8 minutes later, Kylie reached hypermart but Natalie was 1008 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hypermart and the school in km.
(a)
From 11 57 to 12 17 = 20 min
Combined speed of the two cyclists
= 1008 ÷ (20 - 8)
= 84 m/min
(b)
Distance between the hypermart and the school
= 20 x 84
= 1680 m
1000 m = 1 km
1680 m = 1.68 km
Distance between the hypermart and the school = 1.68 km
Answer(s): (a) 84 m/min; (b) 1.68 km
