At 7 a.m., Henry and Liam left Park G and drove towards Park H at average speeds of 80 km/h and 56 km/h respectively. Upon reaching Park H, Henry rested for 2 hours. He then headed back for Park G at an average speed of 80 km/h along the same route. Henry and Liam met each other on their way at 1 p.m.
- How far had Henry covered when he met Liam on the way?
- How far apart were the two parks?
(a)
Time taken by Liam = 6 h
Time taken by Henry = 6 - 2 = 4 h
Distance covered by Henry when he met Liam
= 4 x 80
= 320 km
(b)
Distance travelled by Liam
= 6 x 56
= 336 km
Distance of the two parks
= (320 + 336) ÷ 2
= 656 ÷ 2
= 328 km
Answer(s): (a) 320 km; (b) 328 km
