Ethan took part in a 40 km cycling race. There was a water refill station at one-quarter the distance of the race.
- Ethan stopped at the water refill station to refill his water bottle. How many kilometres was he away from the starting point to the water refill station?
- After passing the water refill station, Ethan cycled 110 of the remaining distance and stopped. How many kilometres was he away from the finishing point?
(a)
Distance from the starting point
= 40 ÷ 4
= 10 km
(b)
Distance from the refill station to the finishing point
= 30 km
The remaining distance from where Ethan stopped to the finishing point
= (1 -
110) x 30
=
910 x 30
= 27 km
Answer(s): (a) 10 km; (b) 27 km
