At 10 57, Ivory cycled from the mall towards the bakery while Cindy cycled from the bakery towards the mall. At 11 14, the two cyclists passed each other. 15 minutes later, Ivory reached bakery but Cindy was 1020 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bakery and the mall in km.
(a)
From 10 57 to 11 14 = 17 min
Combined speed of the two cyclists
= 1020 ÷ (17 - 15)
= 510 m/min
(b)
Distance between the bakery and the mall
= 17 x 510
= 8670 m
1000 m = 1 km
8670 m = 8.67 km
Distance between the bakery and the mall = 8.67 km
Answer(s): (a) 510 m/min; (b) 8.67 km
