At 9 a.m., Perry and Julian left Park U and drove towards Park V at average speeds of 98 km/h and 63 km/h respectively. Upon reaching Park V, Perry rested for 3 hours. He then headed back for Park U at an average speed of 98 km/h along the same route. Perry and Julian met each other on their way at 1 p.m.
- How far had Perry covered when he met Julian on the way?
- How far apart were the two parks?
(a)
Time taken by Julian = 4 h
Time taken by Perry = 4 - 3 = 1 h
Distance covered by Perry when he met Julian
= 1 x 98
= 98 km
(b)
Distance travelled by Julian
= 4 x 63
= 252 km
Distance of the two parks
= (98 + 252) ÷ 2
= 350 ÷ 2
= 175 km
Answer(s): (a) 98 km; (b) 175 km
