At 13 51, Diana cycled from the temple towards the playground while Xuan cycled from the playground towards the temple. At 14 11, the two cyclists passed each other. 11 minutes later, Diana reached playground but Xuan was 1152 m from the temple.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the playground and the temple in km.
(a)
From 13 51 to 14 11 = 20 min
Combined speed of the two cyclists
= 1152 ÷ (20 - 11)
= 128 m/min
(b)
Distance between the playground and the temple
= 20 x 128
= 2560 m
1000 m = 1 km
2560 m = 2.56 km
Distance between the playground and the temple = 2.56 km
Answer(s): (a) 128 m/min; (b) 2.56 km
