At 11 52, Lucy cycled from the museum towards the mall while Xylia cycled from the mall towards the museum. At 12 12, the two cyclists passed each other. 15 minutes later, Lucy reached mall but Xylia was 900 m from the museum.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mall and the museum in km.
(a)
From 11 52 to 12 12 = 20 min
Combined speed of the two cyclists
= 900 ÷ (20 - 15)
= 180 m/min
(b)
Distance between the mall and the museum
= 20 x 180
= 3600 m
1000 m = 1 km
3600 m = 3.6 km
Distance between the mall and the museum = 3.6 km
Answer(s): (a) 180 m/min; (b) 3.6 km
