At 7 a.m., Liam and Jenson left Park Y and drove towards Park Z at average speeds of 92 km/h and 56 km/h respectively. Upon reaching Park Z, Liam rested for 2 hours. He then headed back for Park Y at an average speed of 92 km/h along the same route. Liam and Jenson met each other on their way at 12 noon.
- How far had Liam covered when he met Jenson on the way?
- How far apart were the two parks?
(a)
Time taken by Jenson = 5 h
Time taken by Liam = 5 - 2 = 3 h
Distance covered by Liam when he met Jenson
= 3 x 92
= 276 km
(b)
Distance travelled by Jenson
= 5 x 56
= 280 km
Distance of the two parks
= (276 + 280) ÷ 2
= 556 ÷ 2
= 278 km
Answer(s): (a) 276 km; (b) 278 km
