At 7 a.m., Ryan and Eric left Park L and drove towards Park M at average speeds of 100 km/h and 62 km/h respectively. Upon reaching Park M, Ryan rested for 2 hours. He then headed back for Park L at an average speed of 100 km/h along the same route. Ryan and Eric met each other on their way at 12 noon.
- How far had Ryan 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 Ryan = 5 - 2 = 3 h
Distance covered by Ryan when he met Eric
= 3 x 100
= 300 km
(b)
Distance travelled by Eric
= 5 x 62
= 310 km
Distance of the two parks
= (300 + 310) ÷ 2
= 610 ÷ 2
= 305 km
Answer(s): (a) 300 km; (b) 305 km
