At 6 a.m., Billy and Sean left Park G and drove towards Park H at average speeds of 96 km/h and 58 km/h respectively. Upon reaching Park H, Billy rested for 2 hours. He then headed back for Park G at an average speed of 96 km/h along the same route. Billy and Sean met each other on their way at 12 noon.
- How far had Billy covered when he met Sean on the way?
- How far apart were the two parks?
(a)
Time taken by Sean = 6 h
Time taken by Billy = 6 - 2 = 4 h
Distance covered by Billy when he met Sean
= 4 x 96
= 384 km
(b)
Distance travelled by Sean
= 6 x 58
= 348 km
Distance of the two parks
= (384 + 348) ÷ 2
= 732 ÷ 2
= 366 km
Answer(s): (a) 384 km; (b) 366 km
