At 5 a.m., Bobby and Nick left Park P and drove towards Park Q at average speeds of 98 km/h and 60 km/h respectively. Upon reaching Park Q, Bobby rested for 3 hours. He then headed back for Park P at an average speed of 98 km/h along the same route. Bobby and Nick met each other on their way at 12 noon.
- How far had Bobby covered when he met Nick on the way?
- How far apart were the two parks?
(a)
Time taken by Nick = 7 h
Time taken by Bobby = 7 - 3 = 4 h
Distance covered by Bobby when he met Nick
= 4 x 98
= 392 km
(b)
Distance travelled by Nick
= 7 x 60
= 420 km
Distance of the two parks
= (392 + 420) ÷ 2
= 812 ÷ 2
= 406 km
Answer(s): (a) 392 km; (b) 406 km
