At 5 a.m., Glen and Bobby left Park N and drove towards Park P at average speeds of 75 km/h and 51 km/h respectively. Upon reaching Park P, Glen rested for 2 hours. He then headed back for Park N at an average speed of 75 km/h along the same route. Glen and Bobby met each other on their way at 12 noon.
- How far had Glen covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 7 h
Time taken by Glen = 7 - 2 = 5 h
Distance covered by Glen when he met Bobby
= 5 x 75
= 375 km
(b)
Distance travelled by Bobby
= 7 x 51
= 357 km
Distance of the two parks
= (375 + 357) ÷ 2
= 732 ÷ 2
= 366 km
Answer(s): (a) 375 km; (b) 366 km
