At 10 57, Emily cycled from the mosque towards the hospital while Gem cycled from the hospital towards the mosque. At 11 17, the two cyclists passed each other. 15 minutes later, Emily reached hospital but Gem was 1110 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the mosque in km.
(a)
From 10 57 to 11 17 = 20 min
Combined speed of the two cyclists
= 1110 ÷ (20 - 15)
= 222 m/min
(b)
Distance between the hospital and the mosque
= 20 x 222
= 4440 m
1000 m = 1 km
4440 m = 4.44 km
Distance between the hospital and the mosque = 4.44 km
Answer(s): (a) 222 m/min; (b) 4.44 km
