At 5 a.m., Tim and Bryan left Park G and drove towards Park H at average speeds of 79 km/h and 64 km/h respectively. Upon reaching Park H, Tim rested for 3 hours. He then headed back for Park G at an average speed of 79 km/h along the same route. Tim and Bryan met each other on their way at 12 noon.
- How far had Tim covered when he met Bryan on the way?
- How far apart were the two parks?
(a)
Time taken by Bryan = 7 h
Time taken by Tim = 7 - 3 = 4 h
Distance covered by Tim when he met Bryan
= 4 x 79
= 316 km
(b)
Distance travelled by Bryan
= 7 x 64
= 448 km
Distance of the two parks
= (316 + 448) ÷ 2
= 764 ÷ 2
= 382 km
Answer(s): (a) 316 km; (b) 382 km
