At 10 57, Usha cycled from the market towards the mall while Fiona cycled from the mall towards the market. At 11 17, the two cyclists passed each other. 15 minutes later, Usha reached mall but Fiona was 915 m from the market.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the mall and the market in km.
(a)
From 10 57 to 11 17 = 20 min
Combined speed of the two cyclists
= 915 ÷ (20 - 15)
= 183 m/min
(b)
Distance between the mall and the market
= 20 x 183
= 3660 m
1000 m = 1 km
3660 m = 3.66 km
Distance between the mall and the market = 3.66 km
Answer(s): (a) 183 m/min; (b) 3.66 km
