At 10 54, Gwen cycled from the school towards the mall while Wendy cycled from the mall towards the school. At 11 14, the two cyclists passed each other. 15 minutes later, Gwen reached mall but Wendy was 1175 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mall and the school in km.
(a)
From 10 54 to 11 14 = 20 min
Combined speed of the two cyclists
= 1175 ÷ (20 - 15)
= 235 m/min
(b)
Distance between the mall and the school
= 20 x 235
= 4700 m
1000 m = 1 km
4700 m = 4.7 km
Distance between the mall and the school = 4.7 km
Answer(s): (a) 235 m/min; (b) 4.7 km
