At 7 a.m., Simon and Julian left Park T and drove towards Park U at average speeds of 72 km/h and 52 km/h respectively. Upon reaching Park U, Simon rested for 2 hours. He then headed back for Park T at an average speed of 72 km/h along the same route. Simon and Julian met each other on their way at 12 noon.
- How far had Simon covered when he met Julian on the way?
- How far apart were the two parks?
(a)
Time taken by Julian = 5 h
Time taken by Simon = 5 - 2 = 3 h
Distance covered by Simon when he met Julian
= 3 x 72
= 216 km
(b)
Distance travelled by Julian
= 5 x 52
= 260 km
Distance of the two parks
= (216 + 260) ÷ 2
= 476 ÷ 2
= 238 km
Answer(s): (a) 216 km; (b) 238 km
