At 7 a.m., Glen and Warren left Park T and drove towards Park U at average speeds of 99 km/h and 55 km/h respectively. Upon reaching Park U, Glen rested for 2 hours. He then headed back for Park T at an average speed of 99 km/h along the same route. Glen and Warren met each other on their way at 2 p.m.
- How far had Glen covered when he met Warren on the way?
- How far apart were the two parks?
(a)
Time taken by Warren = 7 h
Time taken by Glen = 7 - 2 = 5 h
Distance covered by Glen when he met Warren
= 5 x 99
= 495 km
(b)
Distance travelled by Warren
= 7 x 55
= 385 km
Distance of the two parks
= (495 + 385) ÷ 2
= 880 ÷ 2
= 440 km
Answer(s): (a) 495 km; (b) 440 km
