At 10 57, Irene cycled from the bakery towards the hypermart while Cindy cycled from the hypermart towards the bakery. At 11 11, the two cyclists passed each other. 10 minutes later, Irene reached hypermart but Cindy was 940 m from the bakery.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hypermart and the bakery in km.
(a)
From 10 57 to 11 11 = 14 min
Combined speed of the two cyclists
= 940 ÷ (14 - 10)
= 235 m/min
(b)
Distance between the hypermart and the bakery
= 14 x 235
= 3290 m
1000 m = 1 km
3290 m = 3.29 km
Distance between the hypermart and the bakery = 3.29 km
Answer(s): (a) 235 m/min; (b) 3.29 km
