At 5 a.m., Asher and Brandon left Park Z and drove towards Park A at average speeds of 83 km/h and 57 km/h respectively. Upon reaching Park A, Asher rested for 2 hours. He then headed back for Park Z at an average speed of 83 km/h along the same route. Asher and Brandon met each other on their way at 12 noon.
- How far had Asher 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 Asher = 7 - 2 = 5 h
Distance covered by Asher when he met Brandon
= 5 x 83
= 415 km
(b)
Distance travelled by Brandon
= 7 x 57
= 399 km
Distance of the two parks
= (415 + 399) ÷ 2
= 814 ÷ 2
= 407 km
Answer(s): (a) 415 km; (b) 407 km
