At 10 56, Irene cycled from the bank towards the mall while Jean cycled from the mall towards the bank. At 11 11, the two cyclists passed each other. 9 minutes later, Irene reached mall but Jean was 1068 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mall and the bank in km.
(a)
From 10 56 to 11 11 = 15 min
Combined speed of the two cyclists
= 1068 ÷ (15 - 9)
= 178 m/min
(b)
Distance between the mall and the bank
= 15 x 178
= 2670 m
1000 m = 1 km
2670 m = 2.67 km
Distance between the mall and the bank = 2.67 km
Answer(s): (a) 178 m/min; (b) 2.67 km
