At 5 a.m., Justin and Jenson left Park H and drove towards Park J at average speeds of 74 km/h and 58 km/h respectively. Upon reaching Park J, Justin rested for 2 hours. He then headed back for Park H at an average speed of 74 km/h along the same route. Justin and Jenson met each other on their way at 12 noon.
- How far had Justin covered when he met Jenson on the way?
- How far apart were the two parks?
(a)
Time taken by Jenson = 7 h
Time taken by Justin = 7 - 2 = 5 h
Distance covered by Justin when he met Jenson
= 5 x 74
= 370 km
(b)
Distance travelled by Jenson
= 7 x 58
= 406 km
Distance of the two parks
= (370 + 406) ÷ 2
= 776 ÷ 2
= 388 km
Answer(s): (a) 370 km; (b) 388 km
