At 5 a.m., Billy and Wesley left Park U and drove towards Park V at average speeds of 70 km/h and 54 km/h respectively. Upon reaching Park V, Billy rested for 2 hours. He then headed back for Park U at an average speed of 70 km/h along the same route. Billy and Wesley met each other on their way at 12 noon.
- How far had Billy covered when he met Wesley on the way?
- How far apart were the two parks?
(a)
Time taken by Wesley = 7 h
Time taken by Billy = 7 - 2 = 5 h
Distance covered by Billy when he met Wesley
= 5 x 70
= 350 km
(b)
Distance travelled by Wesley
= 7 x 54
= 378 km
Distance of the two parks
= (350 + 378) ÷ 2
= 728 ÷ 2
= 364 km
Answer(s): (a) 350 km; (b) 364 km
