At 10 55, Shiyun cycled from the school towards the hospital while Emma cycled from the hospital towards the school. At 11 15, the two cyclists passed each other. 13 minutes later, Shiyun reached hospital but Emma was 987 m from the school.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the school in km.
(a)
From 10 55 to 11 15 = 20 min
Combined speed of the two cyclists
= 987 ÷ (20 - 13)
= 141 m/min
(b)
Distance between the hospital and the school
= 20 x 141
= 2820 m
1000 m = 1 km
2820 m = 2.82 km
Distance between the hospital and the school = 2.82 km
Answer(s): (a) 141 m/min; (b) 2.82 km
