At 7 a.m., Elijah and Daniel left Park G and drove towards Park H at average speeds of 77 km/h and 51 km/h respectively. Upon reaching Park H, Elijah rested for 2 hours. He then headed back for Park G at an average speed of 77 km/h along the same route. Elijah and Daniel met each other on their way at 12 noon.
- How far had Elijah covered when he met Daniel on the way?
- How far apart were the two parks?
(a)
Time taken by Daniel = 5 h
Time taken by Elijah = 5 - 2 = 3 h
Distance covered by Elijah when he met Daniel
= 3 x 77
= 231 km
(b)
Distance travelled by Daniel
= 5 x 51
= 255 km
Distance of the two parks
= (231 + 255) ÷ 2
= 486 ÷ 2
= 243 km
Answer(s): (a) 231 km; (b) 243 km
