At 7 a.m., Seth and Gabriel left Park F and drove towards Park G at average speeds of 86 km/h and 60 km/h respectively. Upon reaching Park G, Seth rested for 2 hours. He then headed back for Park F at an average speed of 86 km/h along the same route. Seth and Gabriel met each other on their way at 2 p.m.
- How far had Seth covered when he met Gabriel on the way?
- How far apart were the two parks?
(a)
Time taken by Gabriel = 7 h
Time taken by Seth = 7 - 2 = 5 h
Distance covered by Seth when he met Gabriel
= 5 x 86
= 430 km
(b)
Distance travelled by Gabriel
= 7 x 60
= 420 km
Distance of the two parks
= (430 + 420) ÷ 2
= 850 ÷ 2
= 425 km
Answer(s): (a) 430 km; (b) 425 km
