At 5 a.m., Harry and Brandon left Park B and drove towards Park C at average speeds of 77 km/h and 54 km/h respectively. Upon reaching Park C, Harry rested for 3 hours. He then headed back for Park B at an average speed of 77 km/h along the same route. Harry and Brandon met each other on their way at 12 noon.
- How far had Harry covered when he met Brandon on the way?
- How far apart were the two parks?
(a)
Time taken by Brandon = 7 h
Time taken by Harry = 7 - 3 = 4 h
Distance covered by Harry when he met Brandon
= 4 x 77
= 308 km
(b)
Distance travelled by Brandon
= 7 x 54
= 378 km
Distance of the two parks
= (308 + 378) ÷ 2
= 686 ÷ 2
= 343 km
Answer(s): (a) 308 km; (b) 343 km
