At 6 a.m., Henry and Will left Park M and drove towards Park N at average speeds of 72 km/h and 56 km/h respectively. Upon reaching Park N, Henry rested for 3 hours. He then headed back for Park M at an average speed of 72 km/h along the same route. Henry and Will met each other on their way at 12 noon.
- How far had Henry 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 Henry = 6 - 3 = 3 h
Distance covered by Henry when he met Will
= 3 x 72
= 216 km
(b)
Distance travelled by Will
= 6 x 56
= 336 km
Distance of the two parks
= (216 + 336) ÷ 2
= 552 ÷ 2
= 276 km
Answer(s): (a) 216 km; (b) 276 km
