At 12 59, Zoe cycled from the mall towards the market while Usha cycled from the market towards the mall. At 13 14, the two cyclists passed each other. 12 minutes later, Zoe reached market but Usha was 1182 m from the mall.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the market and the mall in km.
(a)
From 12 59 to 13 14 = 15 min
Combined speed of the two cyclists
= 1182 ÷ (15 - 12)
= 394 m/min
(b)
Distance between the market and the mall
= 15 x 394
= 5910 m
1000 m = 1 km
5910 m = 5.91 km
Distance between the market and the mall = 5.91 km
Answer(s): (a) 394 m/min; (b) 5.91 km
