At 5 a.m., Henry and Nick left Park B and drove towards Park C at average speeds of 92 km/h and 64 km/h respectively. Upon reaching Park C, Henry rested for 3 hours. He then headed back for Park B at an average speed of 92 km/h along the same route. Henry and Nick met each other on their way at 2 p.m.
- How far had Henry covered when he met Nick on the way?
- How far apart were the two parks?
(a)
Time taken by Nick = 9 h
Time taken by Henry = 9 - 3 = 6 h
Distance covered by Henry when he met Nick
= 6 x 92
= 552 km
(b)
Distance travelled by Nick
= 9 x 64
= 576 km
Distance of the two parks
= (552 + 576) ÷ 2
= 1128 ÷ 2
= 564 km
Answer(s): (a) 552 km; (b) 564 km
