At 10 56, Usha cycled from the school towards the cafe while Barbara cycled from the cafe towards the school. At 11 11, the two cyclists passed each other. 10 minutes later, Usha reached cafe but Barbara was 1190 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the cafe and the school in km.
(a)
From 10 56 to 11 11 = 15 min
Combined speed of the two cyclists
= 1190 ÷ (15 - 10)
= 238 m/min
(b)
Distance between the cafe and the school
= 15 x 238
= 3570 m
1000 m = 1 km
3570 m = 3.57 km
Distance between the cafe and the school = 3.57 km
Answer(s): (a) 238 m/min; (b) 3.57 km
