At 13 55, Tammy cycled from the bank towards the playground while Kylie cycled from the playground towards the bank. At 14 12, the two cyclists passed each other. 8 minutes later, Tammy reached playground but Kylie was 900 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the bank in km.
(a)
From 13 55 to 14 12 = 17 min
Combined speed of the two cyclists
= 900 ÷ (17 - 8)
= 100 m/min
(b)
Distance between the playground and the bank
= 17 x 100
= 1700 m
1000 m = 1 km
1700 m = 1.7 km
Distance between the playground and the bank = 1.7 km
Answer(s): (a) 100 m/min; (b) 1.7 km
