At 13 57, Tammy cycled from the mall towards the boutique while Sarah cycled from the boutique towards the mall. At 14 11, the two cyclists passed each other. 12 minutes later, Tammy reached boutique but Sarah was 900 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the boutique and the mall in km.
(a)
From 13 57 to 14 11 = 14 min
Combined speed of the two cyclists
= 900 ÷ (14 - 12)
= 450 m/min
(b)
Distance between the boutique and the mall
= 14 x 450
= 6300 m
1000 m = 1 km
6300 m = 6.3 km
Distance between the boutique and the mall = 6.3 km
Answer(s): (a) 450 m/min; (b) 6.3 km
