At 9 a.m., Harry and Seth left Park U and drove towards Park V at average speeds of 86 km/h and 63 km/h respectively. Upon reaching Park V, Harry rested for 2 hours. He then headed back for Park U at an average speed of 86 km/h along the same route. Harry and Seth met each other on their way at 1 p.m.
- How far had Harry covered when he met Seth on the way?
- How far apart were the two parks?
(a)
Time taken by Seth = 4 h
Time taken by Harry = 4 - 2 = 2 h
Distance covered by Harry when he met Seth
= 2 x 86
= 172 km
(b)
Distance travelled by Seth
= 4 x 63
= 252 km
Distance of the two parks
= (172 + 252) ÷ 2
= 424 ÷ 2
= 212 km
Answer(s): (a) 172 km; (b) 212 km
