At 5 a.m., Elijah and Perry left Park E and drove towards Park F at average speeds of 85 km/h and 59 km/h respectively. Upon reaching Park F, Elijah rested for 2 hours. He then headed back for Park E at an average speed of 85 km/h along the same route. Elijah and Perry met each other on their way at 12 noon.
- How far had Elijah covered when he met Perry on the way?
- How far apart were the two parks?
(a)
Time taken by Perry = 7 h
Time taken by Elijah = 7 - 2 = 5 h
Distance covered by Elijah when he met Perry
= 5 x 85
= 425 km
(b)
Distance travelled by Perry
= 7 x 59
= 413 km
Distance of the two parks
= (425 + 413) ÷ 2
= 838 ÷ 2
= 419 km
Answer(s): (a) 425 km; (b) 419 km
