At 6 a.m., Daniel and Oscar left Park U and drove towards Park V at average speeds of 81 km/h and 60 km/h respectively. Upon reaching Park V, Daniel rested for 3 hours. He then headed back for Park U at an average speed of 81 km/h along the same route. Daniel and Oscar met each other on their way at 1 p.m.
- How far had Daniel 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 Daniel = 7 - 3 = 4 h
Distance covered by Daniel when he met Oscar
= 4 x 81
= 324 km
(b)
Distance travelled by Oscar
= 7 x 60
= 420 km
Distance of the two parks
= (324 + 420) ÷ 2
= 744 ÷ 2
= 372 km
Answer(s): (a) 324 km; (b) 372 km
