At 6 a.m., Ivan and Paul left Park F and drove towards Park G at average speeds of 74 km/h and 53 km/h respectively. Upon reaching Park G, Ivan rested for 2 hours. He then headed back for Park F at an average speed of 74 km/h along the same route. Ivan and Paul met each other on their way at 12 noon.
- How far had Ivan covered when he met Paul on the way?
- How far apart were the two parks?
(a)
Time taken by Paul = 6 h
Time taken by Ivan = 6 - 2 = 4 h
Distance covered by Ivan when he met Paul
= 4 x 74
= 296 km
(b)
Distance travelled by Paul
= 6 x 53
= 318 km
Distance of the two parks
= (296 + 318) ÷ 2
= 614 ÷ 2
= 307 km
Answer(s): (a) 296 km; (b) 307 km
