At 13 57, Rachel cycled from the grocery store towards the park while Sabrina cycled from the park towards the grocery store. At 14 11, the two cyclists passed each other. 12 minutes later, Rachel reached park but Sabrina was 1090 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the park and the grocery store in km.
(a)
From 13 57 to 14 11 = 14 min
Combined speed of the two cyclists
= 1090 ÷ (14 - 12)
= 545 m/min
(b)
Distance between the park and the grocery store
= 14 x 545
= 7630 m
1000 m = 1 km
7630 m = 7.63 km
Distance between the park and the grocery store = 7.63 km
Answer(s): (a) 545 m/min; (b) 7.63 km
