At 13 59, Gabby cycled from the playground towards the bank while Dana cycled from the bank towards the playground. At 14 12, the two cyclists passed each other. 7 minutes later, Gabby reached bank but Dana was 1200 m from the playground.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bank and the playground in km.
(a)
From 13 59 to 14 12 = 13 min
Combined speed of the two cyclists
= 1200 ÷ (13 - 7)
= 200 m/min
(b)
Distance between the bank and the playground
= 13 x 200
= 2600 m
1000 m = 1 km
2600 m = 2.6 km
Distance between the bank and the playground = 2.6 km
Answer(s): (a) 200 m/min; (b) 2.6 km
