At 13 59, Yen cycled from the mosque towards the bakery while Eva cycled from the bakery towards the mosque. At 14 19, the two cyclists passed each other. 11 minutes later, Yen reached bakery but Eva was 1143 m from the mosque.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bakery and the mosque in km.
(a)
From 13 59 to 14 19 = 20 min
Combined speed of the two cyclists
= 1143 ÷ (20 - 11)
= 127 m/min
(b)
Distance between the bakery and the mosque
= 20 x 127
= 2540 m
1000 m = 1 km
2540 m = 2.54 km
Distance between the bakery and the mosque = 2.54 km
Answer(s): (a) 127 m/min; (b) 2.54 km
