At 9 a.m., Daniel and Jenson left Park K and drove towards Park L at average speeds of 86 km/h and 54 km/h respectively. Upon reaching Park L, Daniel rested for 2 hours. He then headed back for Park K at an average speed of 86 km/h along the same route. Daniel and Jenson met each other on their way at 2 p.m.
- How far had Daniel 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 Daniel = 5 - 2 = 3 h
Distance covered by Daniel when he met Jenson
= 3 x 86
= 258 km
(b)
Distance travelled by Jenson
= 5 x 54
= 270 km
Distance of the two parks
= (258 + 270) ÷ 2
= 528 ÷ 2
= 264 km
Answer(s): (a) 258 km; (b) 264 km
