At 12 53, Tina cycled from the mosque towards the hypermart while Diana cycled from the hypermart towards the mosque. At 13 13, the two cyclists passed each other. 13 minutes later, Tina reached hypermart but Diana was 917 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hypermart and the mosque in km.
(a)
From 12 53 to 13 13 = 20 min
Combined speed of the two cyclists
= 917 ÷ (20 - 13)
= 131 m/min
(b)
Distance between the hypermart and the mosque
= 20 x 131
= 2620 m
1000 m = 1 km
2620 m = 2.62 km
Distance between the hypermart and the mosque = 2.62 km
Answer(s): (a) 131 m/min; (b) 2.62 km
