At 7 a.m., Oscar and Ken left Park T and drove towards Park U at average speeds of 94 km/h and 63 km/h respectively. Upon reaching Park U, Oscar rested for 2 hours. He then headed back for Park T at an average speed of 94 km/h along the same route. Oscar and Ken met each other on their way at 1 p.m.
- How far had Oscar covered when he met Ken on the way?
- How far apart were the two parks?
(a)
Time taken by Ken = 6 h
Time taken by Oscar = 6 - 2 = 4 h
Distance covered by Oscar when he met Ken
= 4 x 94
= 376 km
(b)
Distance travelled by Ken
= 6 x 63
= 378 km
Distance of the two parks
= (376 + 378) ÷ 2
= 754 ÷ 2
= 377 km
Answer(s): (a) 376 km; (b) 377 km
