At 8 a.m., Tim and Ivan left Park V and drove towards Park W at average speeds of 72 km/h and 62 km/h respectively. Upon reaching Park W, Tim rested for 2 hours. He then headed back for Park V at an average speed of 72 km/h along the same route. Tim and Ivan met each other on their way at 2 p.m.
- How far had Tim covered when he met Ivan on the way?
- How far apart were the two parks?
(a)
Time taken by Ivan = 6 h
Time taken by Tim = 6 - 2 = 4 h
Distance covered by Tim when he met Ivan
= 4 x 72
= 288 km
(b)
Distance travelled by Ivan
= 6 x 62
= 372 km
Distance of the two parks
= (288 + 372) ÷ 2
= 660 ÷ 2
= 330 km
Answer(s): (a) 288 km; (b) 330 km
