Eric took part in a 30 km cycling race. There was a water refill station at one-quarter the distance of the race.
- Eric 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, Eric cycled 710 of the remaining distance and stopped. How many kilometres was he away from the finishing point?
(a)
Distance from the starting point
= 30 ÷ 4
= 7.5 km
(b)
Distance from the refill station to the finishing point
= 22.5 km
The remaining distance from where Eric stopped to the finishing point
= (1 -
710) x 22.5
=
310 x 22.5
= 6.75 km
Answer(s): (a) 7.5 km; (b) 6.75 km
