At 5 a.m., Elijah and Wesley left Park N and drove towards Park P at average speeds of 87 km/h and 53 km/h respectively. Upon reaching Park P, Elijah rested for 2 hours. He then headed back for Park N at an average speed of 87 km/h along the same route. Elijah and Wesley met each other on their way at 1 p.m.
- How far had Elijah covered when he met Wesley on the way?
- How far apart were the two parks?
(a)
Time taken by Wesley = 8 h
Time taken by Elijah = 8 - 2 = 6 h
Distance covered by Elijah when he met Wesley
= 6 x 87
= 522 km
(b)
Distance travelled by Wesley
= 8 x 53
= 424 km
Distance of the two parks
= (522 + 424) ÷ 2
= 946 ÷ 2
= 473 km
Answer(s): (a) 522 km; (b) 473 km
