At 7 a.m., Harry and Peter left Park Y and drove towards Park Z at average speeds of 88 km/h and 62 km/h respectively. Upon reaching Park Z, Harry rested for 2 hours. He then headed back for Park Y at an average speed of 88 km/h along the same route. Harry and Peter met each other on their way at 2 p.m.
- How far had Harry covered when he met Peter on the way?
- How far apart were the two parks?
(a)
Time taken by Peter = 7 h
Time taken by Harry = 7 - 2 = 5 h
Distance covered by Harry when he met Peter
= 5 x 88
= 440 km
(b)
Distance travelled by Peter
= 7 x 62
= 434 km
Distance of the two parks
= (440 + 434) ÷ 2
= 874 ÷ 2
= 437 km
Answer(s): (a) 440 km; (b) 437 km
