At 7 a.m., Justin and Daniel left Park R and drove towards Park S at average speeds of 80 km/h and 58 km/h respectively. Upon reaching Park S, Justin rested for 2 hours. He then headed back for Park R at an average speed of 80 km/h along the same route. Justin and Daniel met each other on their way at 12 noon.
- How far had Justin covered when he met Daniel on the way?
- How far apart were the two parks?
(a)
Time taken by Daniel = 5 h
Time taken by Justin = 5 - 2 = 3 h
Distance covered by Justin when he met Daniel
= 3 x 80
= 240 km
(b)
Distance travelled by Daniel
= 5 x 58
= 290 km
Distance of the two parks
= (240 + 290) ÷ 2
= 530 ÷ 2
= 265 km
Answer(s): (a) 240 km; (b) 265 km
