At 6 a.m., John and Howard left Park W and drove towards Park X at average speeds of 90 km/h and 56 km/h respectively. Upon reaching Park X, John rested for 3 hours. He then headed back for Park W at an average speed of 90 km/h along the same route. John and Howard met each other on their way at 2 p.m.
- How far had John covered when he met Howard on the way?
- How far apart were the two parks?
(a)
Time taken by Howard = 8 h
Time taken by John = 8 - 3 = 5 h
Distance covered by John when he met Howard
= 5 x 90
= 450 km
(b)
Distance travelled by Howard
= 8 x 56
= 448 km
Distance of the two parks
= (450 + 448) ÷ 2
= 898 ÷ 2
= 449 km
Answer(s): (a) 450 km; (b) 449 km
