At 7 a.m., Gabriel and Zeph left Park J and drove towards Park K at average speeds of 71 km/h and 51 km/h respectively. Upon reaching Park K, Gabriel rested for 2 hours. He then headed back for Park J at an average speed of 71 km/h along the same route. Gabriel and Zeph met each other on their way at 12 noon.
- How far had Gabriel covered when he met Zeph on the way?
- How far apart were the two parks?
(a)
Time taken by Zeph = 5 h
Time taken by Gabriel = 5 - 2 = 3 h
Distance covered by Gabriel when he met Zeph
= 3 x 71
= 213 km
(b)
Distance travelled by Zeph
= 5 x 51
= 255 km
Distance of the two parks
= (213 + 255) ÷ 2
= 468 ÷ 2
= 234 km
Answer(s): (a) 213 km; (b) 234 km
