At 7 a.m., Will and Tom left Park Z and drove towards Park A at average speeds of 87 km/h and 52 km/h respectively. Upon reaching Park A, Will rested for 2 hours. He then headed back for Park Z at an average speed of 87 km/h along the same route. Will and Tom met each other on their way at 1 p.m.
- How far had Will covered when he met Tom on the way?
- How far apart were the two parks?
(a)
Time taken by Tom = 6 h
Time taken by Will = 6 - 2 = 4 h
Distance covered by Will when he met Tom
= 4 x 87
= 348 km
(b)
Distance travelled by Tom
= 6 x 52
= 312 km
Distance of the two parks
= (348 + 312) ÷ 2
= 660 ÷ 2
= 330 km
Answer(s): (a) 348 km; (b) 330 km
