At 6 a.m., Will and Oscar left Park T and drove towards Park U at average speeds of 77 km/h and 54 km/h respectively. Upon reaching Park U, Will rested for 3 hours. He then headed back for Park T at an average speed of 77 km/h along the same route. Will and Oscar met each other on their way at 1 p.m.
- How far had Will covered when he met Oscar on the way?
- How far apart were the two parks?
(a)
Time taken by Oscar = 7 h
Time taken by Will = 7 - 3 = 4 h
Distance covered by Will when he met Oscar
= 4 x 77
= 308 km
(b)
Distance travelled by Oscar
= 7 x 54
= 378 km
Distance of the two parks
= (308 + 378) ÷ 2
= 686 ÷ 2
= 343 km
Answer(s): (a) 308 km; (b) 343 km
