At 12 59, Tiffany cycled from the boutique towards the grocery store while Cathy cycled from the grocery store towards the boutique. At 13 19, the two cyclists passed each other. 15 minutes later, Tiffany reached grocery store but Cathy was 1085 m from the boutique.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the boutique in km.
(a)
From 12 59 to 13 19 = 20 min
Combined speed of the two cyclists
= 1085 ÷ (20 - 15)
= 217 m/min
(b)
Distance between the grocery store and the boutique
= 20 x 217
= 4340 m
1000 m = 1 km
4340 m = 4.34 km
Distance between the grocery store and the boutique = 4.34 km
Answer(s): (a) 217 m/min; (b) 4.34 km
