At 5 a.m., David and Will left Park T and drove towards Park U at average speeds of 84 km/h and 62 km/h respectively. Upon reaching Park U, David rested for 3 hours. He then headed back for Park T at an average speed of 84 km/h along the same route. David and Will met each other on their way at 12 noon.
- How far had David covered when he met Will on the way?
- How far apart were the two parks?
(a)
Time taken by Will = 7 h
Time taken by David = 7 - 3 = 4 h
Distance covered by David when he met Will
= 4 x 84
= 336 km
(b)
Distance travelled by Will
= 7 x 62
= 434 km
Distance of the two parks
= (336 + 434) ÷ 2
= 770 ÷ 2
= 385 km
Answer(s): (a) 336 km; (b) 385 km
