At 6 a.m., Oscar and Perry left Park U and drove towards Park V at average speeds of 76 km/h and 56 km/h respectively. Upon reaching Park V, Oscar rested for 3 hours. He then headed back for Park U at an average speed of 76 km/h along the same route. Oscar and Perry met each other on their way at 1 p.m.
- How far had Oscar covered when he met Perry on the way?
- How far apart were the two parks?
(a)
Time taken by Perry = 7 h
Time taken by Oscar = 7 - 3 = 4 h
Distance covered by Oscar when he met Perry
= 4 x 76
= 304 km
(b)
Distance travelled by Perry
= 7 x 56
= 392 km
Distance of the two parks
= (304 + 392) ÷ 2
= 696 ÷ 2
= 348 km
Answer(s): (a) 304 km; (b) 348 km
