At 13 55, Gem cycled from the mall towards the hospital while Nicole cycled from the hospital towards the mall. At 14 13, the two cyclists passed each other. 14 minutes later, Gem reached hospital but Nicole was 1100 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the mall in km.
(a)
From 13 55 to 14 13 = 18 min
Combined speed of the two cyclists
= 1100 ÷ (18 - 14)
= 275 m/min
(b)
Distance between the hospital and the mall
= 18 x 275
= 4950 m
1000 m = 1 km
4950 m = 4.95 km
Distance between the hospital and the mall = 4.95 km
Answer(s): (a) 275 m/min; (b) 4.95 km
