At 6 a.m., Simon and Henry left Park B and drove towards Park C at average speeds of 83 km/h and 60 km/h respectively. Upon reaching Park C, Simon rested for 3 hours. He then headed back for Park B at an average speed of 83 km/h along the same route. Simon and Henry met each other on their way at 1 p.m.
- How far had Simon covered when he met Henry on the way?
- How far apart were the two parks?
(a)
Time taken by Henry = 7 h
Time taken by Simon = 7 - 3 = 4 h
Distance covered by Simon when he met Henry
= 4 x 83
= 332 km
(b)
Distance travelled by Henry
= 7 x 60
= 420 km
Distance of the two parks
= (332 + 420) ÷ 2
= 752 ÷ 2
= 376 km
Answer(s): (a) 332 km; (b) 376 km
