At 5 a.m., Caden and Eric left Park H and drove towards Park J at average speeds of 70 km/h and 58 km/h respectively. Upon reaching Park J, Caden rested for 3 hours. He then headed back for Park H at an average speed of 70 km/h along the same route. Caden and Eric met each other on their way at 2 p.m.
- How far had Caden covered when he met Eric on the way?
- How far apart were the two parks?
(a)
Time taken by Eric = 9 h
Time taken by Caden = 9 - 3 = 6 h
Distance covered by Caden when he met Eric
= 6 x 70
= 420 km
(b)
Distance travelled by Eric
= 9 x 58
= 522 km
Distance of the two parks
= (420 + 522) ÷ 2
= 942 ÷ 2
= 471 km
Answer(s): (a) 420 km; (b) 471 km
