At 11 59, Ivory cycled from the bakery towards the grocery store while Marion cycled from the grocery store towards the bakery. At 12 16, the two cyclists passed each other. 15 minutes later, Ivory reached grocery store but Marion was 1180 m from the bakery.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the grocery store and the bakery in km.
(a)
From 11 59 to 12 16 = 17 min
Combined speed of the two cyclists
= 1180 ÷ (17 - 15)
= 590 m/min
(b)
Distance between the grocery store and the bakery
= 17 x 590
= 10030 m
1000 m = 1 km
10030 m = 10.03 km
Distance between the grocery store and the bakery = 10.03 km
Answer(s): (a) 590 m/min; (b) 10.03 km
