At 5 a.m., Fabian and Riordan left Park M and drove towards Park N at average speeds of 72 km/h and 52 km/h respectively. Upon reaching Park N, Fabian rested for 3 hours. He then headed back for Park M at an average speed of 72 km/h along the same route. Fabian and Riordan met each other on their way at 12 noon.
- How far had Fabian covered when he met Riordan on the way?
- How far apart were the two parks?
(a)
Time taken by Riordan = 7 h
Time taken by Fabian = 7 - 3 = 4 h
Distance covered by Fabian when he met Riordan
= 4 x 72
= 288 km
(b)
Distance travelled by Riordan
= 7 x 52
= 364 km
Distance of the two parks
= (288 + 364) ÷ 2
= 652 ÷ 2
= 326 km
Answer(s): (a) 288 km; (b) 326 km
