At 8 a.m., Glen and Henry left Park Z and drove towards Park A at average speeds of 81 km/h and 59 km/h respectively. Upon reaching Park A, Glen rested for 2 hours. He then headed back for Park Z at an average speed of 81 km/h along the same route. Glen and Henry met each other on their way at 2 p.m.
- How far had Glen covered when he met Henry on the way?
- How far apart were the two parks?
(a)
Time taken by Henry = 6 h
Time taken by Glen = 6 - 2 = 4 h
Distance covered by Glen when he met Henry
= 4 x 81
= 324 km
(b)
Distance travelled by Henry
= 6 x 59
= 354 km
Distance of the two parks
= (324 + 354) ÷ 2
= 678 ÷ 2
= 339 km
Answer(s): (a) 324 km; (b) 339 km
