At 7 a.m., Bryan and Eric left Park P and drove towards Park Q at average speeds of 72 km/h and 64 km/h respectively. Upon reaching Park Q, Bryan rested for 3 hours. He then headed back for Park P at an average speed of 72 km/h along the same route. Bryan and Eric met each other on their way at 12 noon.
- How far had Bryan covered when he met Eric on the way?
- How far apart were the two parks?
(a)
Time taken by Eric = 5 h
Time taken by Bryan = 5 - 3 = 2 h
Distance covered by Bryan when he met Eric
= 2 x 72
= 144 km
(b)
Distance travelled by Eric
= 5 x 64
= 320 km
Distance of the two parks
= (144 + 320) ÷ 2
= 464 ÷ 2
= 232 km
Answer(s): (a) 144 km; (b) 232 km
