At 5 a.m., Bryan and Andy left Park C and drove towards Park D at average speeds of 98 km/h and 52 km/h respectively. Upon reaching Park D, Bryan rested for 3 hours. He then headed back for Park C at an average speed of 98 km/h along the same route. Bryan and Andy met each other on their way at 12 noon.
- How far had Bryan covered when he met Andy on the way?
- How far apart were the two parks?
(a)
Time taken by Andy = 7 h
Time taken by Bryan = 7 - 3 = 4 h
Distance covered by Bryan when he met Andy
= 4 x 98
= 392 km
(b)
Distance travelled by Andy
= 7 x 52
= 364 km
Distance of the two parks
= (392 + 364) ÷ 2
= 756 ÷ 2
= 378 km
Answer(s): (a) 392 km; (b) 378 km
