At 13 59, Zoe cycled from the bank towards the mosque while Cindy cycled from the mosque towards the bank. At 14 19, the two cyclists passed each other. 15 minutes later, Zoe reached mosque but Cindy was 1170 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mosque and the bank in km.
(a)
From 13 59 to 14 19 = 20 min
Combined speed of the two cyclists
= 1170 ÷ (20 - 15)
= 234 m/min
(b)
Distance between the mosque and the bank
= 20 x 234
= 4680 m
1000 m = 1 km
4680 m = 4.68 km
Distance between the mosque and the bank = 4.68 km
Answer(s): (a) 234 m/min; (b) 4.68 km
