At 5 a.m., Simon and Dylan left Park W and drove towards Park X at average speeds of 90 km/h and 58 km/h respectively. Upon reaching Park X, Simon rested for 3 hours. He then headed back for Park W at an average speed of 90 km/h along the same route. Simon and Dylan met each other on their way at 1 p.m.
- How far had Simon covered when he met Dylan on the way?
- How far apart were the two parks?
(a)
Time taken by Dylan = 8 h
Time taken by Simon = 8 - 3 = 5 h
Distance covered by Simon when he met Dylan
= 5 x 90
= 450 km
(b)
Distance travelled by Dylan
= 8 x 58
= 464 km
Distance of the two parks
= (450 + 464) ÷ 2
= 914 ÷ 2
= 457 km
Answer(s): (a) 450 km; (b) 457 km
