At 8 a.m., Glen and Billy left Park U and drove towards Park V at average speeds of 88 km/h and 56 km/h respectively. Upon reaching Park V, Glen rested for 3 hours. He then headed back for Park U at an average speed of 88 km/h along the same route. Glen and Billy met each other on their way at 1 p.m.
- How far had Glen covered when he met Billy on the way?
- How far apart were the two parks?
(a)
Time taken by Billy = 5 h
Time taken by Glen = 5 - 3 = 2 h
Distance covered by Glen when he met Billy
= 2 x 88
= 176 km
(b)
Distance travelled by Billy
= 5 x 56
= 280 km
Distance of the two parks
= (176 + 280) ÷ 2
= 456 ÷ 2
= 228 km
Answer(s): (a) 176 km; (b) 228 km
