At 13 55, Emily cycled from the bank towards the bakery while Jane cycled from the bakery towards the bank. At 14 15, the two cyclists passed each other. 15 minutes later, Emily reached bakery but Jane was 1180 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bakery and the bank in km.
(a)
From 13 55 to 14 15 = 20 min
Combined speed of the two cyclists
= 1180 ÷ (20 - 15)
= 236 m/min
(b)
Distance between the bakery and the bank
= 20 x 236
= 4720 m
1000 m = 1 km
4720 m = 4.72 km
Distance between the bakery and the bank = 4.72 km
Answer(s): (a) 236 m/min; (b) 4.72 km
