At 10 56, Opal cycled from the school towards the bistro while Hazel cycled from the bistro towards the school. At 11 16, the two cyclists passed each other. 11 minutes later, Opal reached bistro but Hazel was 1080 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bistro and the school in km.
(a)
From 10 56 to 11 16 = 20 min
Combined speed of the two cyclists
= 1080 ÷ (20 - 11)
= 120 m/min
(b)
Distance between the bistro and the school
= 20 x 120
= 2400 m
1000 m = 1 km
2400 m = 2.4 km
Distance between the bistro and the school = 2.4 km
Answer(s): (a) 120 m/min; (b) 2.4 km
