At 06 25, Nicole left Town K and cycled towards Town L. Linda left Town K and cycled towards Town L at 06 45. Linda's cycling speed was 3 km/h faster than Nicole. At 10 25, Linda caught up with Nicole. Find the cycling speed of each cyclist.
- Nicole
- Linda
(a)
Duration that Linda cycled from 06 45 to 10 25
= 3
4060 = 3
23 h
Distance that Linda cycled more than Nicole
= 3
23 x 3
= 11 km
However, since Nicole left 20 minutes earlier than Linda and Linda caught up with Nicole, it means that Nicole has cycled 11 km in 20 min.
1 h = 60 min
20 min = 20 ÷ 60 =
13 h
Nicole's cycling speed
= 11 ÷
13 = 11 x
31 = 33 km/h
(b)
Linda's cycling speed
= 33 + 3
= 36 km/h
Answer(s): (a) 33 km/h ; (b) 36 km/h
