At 5 a.m., Archie and Ivan left Park U and drove towards Park V at average speeds of 70 km/h and 60 km/h respectively. Upon reaching Park V, Archie rested for 3 hours. He then headed back for Park U at an average speed of 70 km/h along the same route. Archie and Ivan met each other on their way at 12 noon.
- How far had Archie covered when he met Ivan on the way?
- How far apart were the two parks?
(a)
Time taken by Ivan = 7 h
Time taken by Archie = 7 - 3 = 4 h
Distance covered by Archie when he met Ivan
= 4 x 70
= 280 km
(b)
Distance travelled by Ivan
= 7 x 60
= 420 km
Distance of the two parks
= (280 + 420) ÷ 2
= 700 ÷ 2
= 350 km
Answer(s): (a) 280 km; (b) 350 km
