At 8 a.m., Glen and Jenson left Park S and drove towards Park T at average speeds of 70 km/h and 64 km/h respectively. Upon reaching Park T, Glen rested for 2 hours. He then headed back for Park S at an average speed of 70 km/h along the same route. Glen and Jenson met each other on their way at 2 p.m.
- How far had Glen covered when he met Jenson on the way?
- How far apart were the two parks?
(a)
Time taken by Jenson = 6 h
Time taken by Glen = 6 - 2 = 4 h
Distance covered by Glen when he met Jenson
= 4 x 70
= 280 km
(b)
Distance travelled by Jenson
= 6 x 64
= 384 km
Distance of the two parks
= (280 + 384) ÷ 2
= 664 ÷ 2
= 332 km
Answer(s): (a) 280 km; (b) 332 km
