At 6 a.m., Will and Tim left Park G and drove towards Park H at average speeds of 72 km/h and 55 km/h respectively. Upon reaching Park H, Will rested for 2 hours. He then headed back for Park G at an average speed of 72 km/h along the same route. Will and Tim met each other on their way at 12 noon.
- How far had Will covered when he met Tim on the way?
- How far apart were the two parks?
(a)
Time taken by Tim = 6 h
Time taken by Will = 6 - 2 = 4 h
Distance covered by Will when he met Tim
= 4 x 72
= 288 km
(b)
Distance travelled by Tim
= 6 x 55
= 330 km
Distance of the two parks
= (288 + 330) ÷ 2
= 618 ÷ 2
= 309 km
Answer(s): (a) 288 km; (b) 309 km
