At 13 58, Emma cycled from the temple towards the mall while Julie cycled from the mall towards the temple. At 14 16, the two cyclists passed each other. 10 minutes later, Emma reached mall but Julie was 1160 m from the temple.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mall and the temple in km.
(a)
From 13 58 to 14 16 = 18 min
Combined speed of the two cyclists
= 1160 ÷ (18 - 10)
= 145 m/min
(b)
Distance between the mall and the temple
= 18 x 145
= 2610 m
1000 m = 1 km
2610 m = 2.61 km
Distance between the mall and the temple = 2.61 km
Answer(s): (a) 145 m/min; (b) 2.61 km
