At 10 55, Yen cycled from the mall towards the clinic while Emily cycled from the clinic towards the mall. At 11 13, the two cyclists passed each other. 14 minutes later, Yen reached clinic but Emily was 1080 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the clinic and the mall in km.
(a)
From 10 55 to 11 13 = 18 min
Combined speed of the two cyclists
= 1080 ÷ (18 - 14)
= 270 m/min
(b)
Distance between the clinic and the mall
= 18 x 270
= 4860 m
1000 m = 1 km
4860 m = 4.86 km
Distance between the clinic and the mall = 4.86 km
Answer(s): (a) 270 m/min; (b) 4.86 km
