At 12 55, Julie cycled from the bank towards the mosque while Jen cycled from the mosque towards the bank. At 13 15, the two cyclists passed each other. 15 minutes later, Julie reached mosque but Jen was 980 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 12 55 to 13 15 = 20 min
Combined speed of the two cyclists
= 980 ÷ (20 - 15)
= 196 m/min
(b)
Distance between the mosque and the bank
= 20 x 196
= 3920 m
1000 m = 1 km
3920 m = 3.92 km
Distance between the mosque and the bank = 3.92 km
Answer(s): (a) 196 m/min; (b) 3.92 km
