At 13 59, Tina cycled from the school towards the farm while Penelope cycled from the farm towards the school. At 14 12, the two cyclists passed each other. 11 minutes later, Tina reached farm but Penelope was 1200 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the farm and the school in km.
(a)
From 13 59 to 14 12 = 13 min
Combined speed of the two cyclists
= 1200 ÷ (13 - 11)
= 600 m/min
(b)
Distance between the farm and the school
= 13 x 600
= 7800 m
1000 m = 1 km
7800 m = 7.8 km
Distance between the farm and the school = 7.8 km
Answer(s): (a) 600 m/min; (b) 7.8 km
