At 13 59, Lynn cycled from the bank towards the hospital while Abi cycled from the hospital towards the bank. At 14 19, the two cyclists passed each other. 7 minutes later, Lynn reached hospital but Abi was 1157 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 13 59 to 14 19 = 20 min
Combined speed of the two cyclists
= 1157 ÷ (20 - 7)
= 89 m/min
(b)
Distance between the hospital and the bank
= 20 x 89
= 1780 m
1000 m = 1 km
1780 m = 1.78 km
Distance between the hospital and the bank = 1.78 km
Answer(s): (a) 89 m/min; (b) 1.78 km
