At 5 a.m., Glen and Albert left Park P and drove towards Park Q at average speeds of 76 km/h and 54 km/h respectively. Upon reaching Park Q, Glen rested for 3 hours. He then headed back for Park P at an average speed of 76 km/h along the same route. Glen and Albert met each other on their way at 12 noon.
- How far had Glen covered when he met Albert on the way?
- How far apart were the two parks?
(a)
Time taken by Albert = 7 h
Time taken by Glen = 7 - 3 = 4 h
Distance covered by Glen when he met Albert
= 4 x 76
= 304 km
(b)
Distance travelled by Albert
= 7 x 54
= 378 km
Distance of the two parks
= (304 + 378) ÷ 2
= 682 ÷ 2
= 341 km
Answer(s): (a) 304 km; (b) 341 km
