At 13 58, Diana cycled from the bank towards the hospital while Kylie cycled from the hospital towards the bank. At 14 18, the two cyclists passed each other. 8 minutes later, Diana reached hospital but Kylie was 1152 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 58 to 14 18 = 20 min
Combined speed of the two cyclists
= 1152 ÷ (20 - 8)
= 96 m/min
(b)
Distance between the hospital and the bank
= 20 x 96
= 1920 m
1000 m = 1 km
1920 m = 1.92 km
Distance between the hospital and the bank = 1.92 km
Answer(s): (a) 96 m/min; (b) 1.92 km
