At 11 59, Jade cycled from the bank towards the hospital while Gwen cycled from the hospital towards the bank. At 12 15, the two cyclists passed each other. 9 minutes later, Jade reached hospital but Gwen was 1155 m from the bank.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the bank in km.
(a)
From 11 59 to 12 15 = 16 min
Combined speed of the two cyclists
= 1155 ÷ (16 - 9)
= 165 m/min
(b)
Distance between the hospital and the bank
= 16 x 165
= 2640 m
1000 m = 1 km
2640 m = 2.64 km
Distance between the hospital and the bank = 2.64 km
Answer(s): (a) 165 m/min; (b) 2.64 km
