At 9 a.m., Eric and Julian left Park J and drove towards Park K at average speeds of 96 km/h and 63 km/h respectively. Upon reaching Park K, Eric rested for 2 hours. He then headed back for Park J at an average speed of 96 km/h along the same route. Eric and Julian met each other on their way at 1 p.m.
- How far had Eric covered when he met Julian on the way?
- How far apart were the two parks?
(a)
Time taken by Julian = 4 h
Time taken by Eric = 4 - 2 = 2 h
Distance covered by Eric when he met Julian
= 2 x 96
= 192 km
(b)
Distance travelled by Julian
= 4 x 63
= 252 km
Distance of the two parks
= (192 + 252) ÷ 2
= 444 ÷ 2
= 222 km
Answer(s): (a) 192 km; (b) 222 km
