At 5 a.m., Archie and Asher left Park T and drove towards Park U at average speeds of 85 km/h and 56 km/h respectively. Upon reaching Park U, Archie rested for 3 hours. He then headed back for Park T at an average speed of 85 km/h along the same route. Archie and Asher met each other on their way at 12 noon.
- How far had Archie covered when he met Asher on the way?
- How far apart were the two parks?
(a)
Time taken by Asher = 7 h
Time taken by Archie = 7 - 3 = 4 h
Distance covered by Archie when he met Asher
= 4 x 85
= 340 km
(b)
Distance travelled by Asher
= 7 x 56
= 392 km
Distance of the two parks
= (340 + 392) ÷ 2
= 732 ÷ 2
= 366 km
Answer(s): (a) 340 km; (b) 366 km
