At 5 a.m., Glen and Tom left Park X and drove towards Park Y at average speeds of 87 km/h and 59 km/h respectively. Upon reaching Park Y, Glen rested for 2 hours. He then headed back for Park X at an average speed of 87 km/h along the same route. Glen and Tom met each other on their way at 12 noon.
- How far had Glen covered when he met Tom on the way?
- How far apart were the two parks?
(a)
Time taken by Tom = 7 h
Time taken by Glen = 7 - 2 = 5 h
Distance covered by Glen when he met Tom
= 5 x 87
= 435 km
(b)
Distance travelled by Tom
= 7 x 59
= 413 km
Distance of the two parks
= (435 + 413) ÷ 2
= 848 ÷ 2
= 424 km
Answer(s): (a) 435 km; (b) 424 km
