At 13 55, Yoko cycled from the school towards the mall while Tina cycled from the mall towards the school. At 14 15, the two cyclists passed each other. 15 minutes later, Yoko reached mall but Tina was 985 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 13 55 to 14 15 = 20 min
Combined speed of the two cyclists
= 985 ÷ (20 - 15)
= 197 m/min
(b)
Distance between the mall and the school
= 20 x 197
= 3940 m
1000 m = 1 km
3940 m = 3.94 km
Distance between the mall and the school = 3.94 km
Answer(s): (a) 197 m/min; (b) 3.94 km
