At 12 59, Usha cycled from the grocery store towards the bistro while Vanessa cycled from the bistro towards the grocery store. At 13 19, the two cyclists passed each other. 10 minutes later, Usha reached bistro but Vanessa was 1050 m from the grocery store.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bistro and the grocery store in km.
(a)
From 12 59 to 13 19 = 20 min
Combined speed of the two cyclists
= 1050 ÷ (20 - 10)
= 105 m/min
(b)
Distance between the bistro and the grocery store
= 20 x 105
= 2100 m
1000 m = 1 km
2100 m = 2.1 km
Distance between the bistro and the grocery store = 2.1 km
Answer(s): (a) 105 m/min; (b) 2.1 km
