At 9 a.m., Gabriel and Carl left Park D and drove towards Park E at average speeds of 70 km/h and 65 km/h respectively. Upon reaching Park E, Gabriel rested for 2 hours. He then headed back for Park D at an average speed of 70 km/h along the same route. Gabriel and Carl met each other on their way at 1 p.m.
- How far had Gabriel covered when he met Carl on the way?
- How far apart were the two parks?
(a)
Time taken by Carl = 4 h
Time taken by Gabriel = 4 - 2 = 2 h
Distance covered by Gabriel when he met Carl
= 2 x 70
= 140 km
(b)
Distance travelled by Carl
= 4 x 65
= 260 km
Distance of the two parks
= (140 + 260) ÷ 2
= 400 ÷ 2
= 200 km
Answer(s): (a) 140 km; (b) 200 km
