At 12 54, Diana cycled from the market towards the hospital while Emily cycled from the hospital towards the market. At 13 14, the two cyclists passed each other. 12 minutes later, Diana reached hospital but Emily was 1016 m from the market.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the hospital and the market in km.
(a)
From 12 54 to 13 14 = 20 min
Combined speed of the two cyclists
= 1016 ÷ (20 - 12)
= 127 m/min
(b)
Distance between the hospital and the market
= 20 x 127
= 2540 m
1000 m = 1 km
2540 m = 2.54 km
Distance between the hospital and the market = 2.54 km
Answer(s): (a) 127 m/min; (b) 2.54 km
