At 5 a.m., Howard and Sean left Park B and drove towards Park C at average speeds of 92 km/h and 60 km/h respectively. Upon reaching Park C, Howard rested for 3 hours. He then headed back for Park B at an average speed of 92 km/h along the same route. Howard and Sean met each other on their way at 12 noon.
- How far had Howard covered when he met Sean on the way?
- How far apart were the two parks?
(a)
Time taken by Sean = 7 h
Time taken by Howard = 7 - 3 = 4 h
Distance covered by Howard when he met Sean
= 4 x 92
= 368 km
(b)
Distance travelled by Sean
= 7 x 60
= 420 km
Distance of the two parks
= (368 + 420) ÷ 2
= 788 ÷ 2
= 394 km
Answer(s): (a) 368 km; (b) 394 km
