At 6 a.m., Charlie and Will left Park C and drove towards Park D at average speeds of 93 km/h and 57 km/h respectively. Upon reaching Park D, Charlie rested for 2 hours. He then headed back for Park C at an average speed of 93 km/h along the same route. Charlie and Will met each other on their way at 12 noon.
- How far had Charlie covered when he met Will on the way?
- How far apart were the two parks?
(a)
Time taken by Will = 6 h
Time taken by Charlie = 6 - 2 = 4 h
Distance covered by Charlie when he met Will
= 4 x 93
= 372 km
(b)
Distance travelled by Will
= 6 x 57
= 342 km
Distance of the two parks
= (372 + 342) ÷ 2
= 714 ÷ 2
= 357 km
Answer(s): (a) 372 km; (b) 357 km
