At 6 a.m., Sean and Tom left Park U and drove towards Park V at average speeds of 100 km/h and 56 km/h respectively. Upon reaching Park V, Sean rested for 2 hours. He then headed back for Park U at an average speed of 100 km/h along the same route. Sean and Tom met each other on their way at 12 noon.
- How far had Sean 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 Sean = 6 - 2 = 4 h
Distance covered by Sean when he met Tom
= 4 x 100
= 400 km
(b)
Distance travelled by Tom
= 6 x 56
= 336 km
Distance of the two parks
= (400 + 336) ÷ 2
= 736 ÷ 2
= 368 km
Answer(s): (a) 400 km; (b) 368 km
