At 6 a.m., Jeremy and Bryan left Park M and drove towards Park N at average speeds of 99 km/h and 63 km/h respectively. Upon reaching Park N, Jeremy rested for 2 hours. He then headed back for Park M at an average speed of 99 km/h along the same route. Jeremy and Bryan met each other on their way at 12 noon.
- How far had Jeremy covered when he met Bryan on the way?
- How far apart were the two parks?
(a)
Time taken by Bryan = 6 h
Time taken by Jeremy = 6 - 2 = 4 h
Distance covered by Jeremy when he met Bryan
= 4 x 99
= 396 km
(b)
Distance travelled by Bryan
= 6 x 63
= 378 km
Distance of the two parks
= (396 + 378) ÷ 2
= 774 ÷ 2
= 387 km
Answer(s): (a) 396 km; (b) 387 km
