At 12 51, Usha cycled from the bakery towards the bistro while Yoko cycled from the bistro towards the bakery. At 13 11, the two cyclists passed each other. 12 minutes later, Usha reached bistro but Yoko was 1152 m from the bakery.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bistro and the bakery in km.
(a)
From 12 51 to 13 11 = 20 min
Combined speed of the two cyclists
= 1152 ÷ (20 - 12)
= 144 m/min
(b)
Distance between the bistro and the bakery
= 20 x 144
= 2880 m
1000 m = 1 km
2880 m = 2.88 km
Distance between the bistro and the bakery = 2.88 km
Answer(s): (a) 144 m/min; (b) 2.88 km
