At 10 57, Eva cycled from the mall towards the market while Emma cycled from the market towards the mall. At 11 12, the two cyclists passed each other. 13 minutes later, Eva reached market but Emma was 1056 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 10 57 to 11 12 = 15 min
Combined speed of the two cyclists
= 1056 ÷ (15 - 13)
= 528 m/min
(b)
Distance between the market and the mall
= 15 x 528
= 7920 m
1000 m = 1 km
7920 m = 7.92 km
Distance between the market and the mall = 7.92 km
Answer(s): (a) 528 m/min; (b) 7.92 km
