At 11 56, Natalie cycled from the hospital towards the bistro while Lucy cycled from the bistro towards the hospital. At 12 11, the two cyclists passed each other. 13 minutes later, Natalie reached bistro but Lucy was 1140 m from the hospital.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bistro and the hospital in km.
(a)
From 11 56 to 12 11 = 15 min
Combined speed of the two cyclists
= 1140 ÷ (15 - 13)
= 570 m/min
(b)
Distance between the bistro and the hospital
= 15 x 570
= 8550 m
1000 m = 1 km
8550 m = 8.55 km
Distance between the bistro and the hospital = 8.55 km
Answer(s): (a) 570 m/min; (b) 8.55 km
