At 8 a.m., Michael and Elijah left Park W and drove towards Park X at average speeds of 85 km/h and 58 km/h respectively. Upon reaching Park X, Michael rested for 2 hours. He then headed back for Park W at an average speed of 85 km/h along the same route. Michael and Elijah met each other on their way at 2 p.m.
- How far had Michael covered when he met Elijah on the way?
- How far apart were the two parks?
(a)
Time taken by Elijah = 6 h
Time taken by Michael = 6 - 2 = 4 h
Distance covered by Michael when he met Elijah
= 4 x 85
= 340 km
(b)
Distance travelled by Elijah
= 6 x 58
= 348 km
Distance of the two parks
= (340 + 348) ÷ 2
= 688 ÷ 2
= 344 km
Answer(s): (a) 340 km; (b) 344 km
