At 13 56, Tammy cycled from the market towards the bank while Emily cycled from the bank towards the market. At 14 16, the two cyclists passed each other. 15 minutes later, Tammy reached bank but Emily was 945 m from the market.
- At what combined speed were the two cyclists approaching each other?
- Find the distance between the bank and the market in km.
(a)
From 13 56 to 14 16 = 20 min
Combined speed of the two cyclists
= 945 ÷ (20 - 15)
= 189 m/min
(b)
Distance between the bank and the market
= 20 x 189
= 3780 m
1000 m = 1 km
3780 m = 3.78 km
Distance between the bank and the market = 3.78 km
Answer(s): (a) 189 m/min; (b) 3.78 km
