At 9 a.m., Daniel and Tim left Park W and drove towards Park X at average speeds of 81 km/h and 53 km/h respectively. Upon reaching Park X, Daniel rested for 2 hours. He then headed back for Park W at an average speed of 81 km/h along the same route. Daniel and Tim met each other on their way at 2 p.m.
- How far had Daniel covered when he met Tim on the way?
- How far apart were the two parks?
(a)
Time taken by Tim = 5 h
Time taken by Daniel = 5 - 2 = 3 h
Distance covered by Daniel when he met Tim
= 3 x 81
= 243 km
(b)
Distance travelled by Tim
= 5 x 53
= 265 km
Distance of the two parks
= (243 + 265) ÷ 2
= 508 ÷ 2
= 254 km
Answer(s): (a) 243 km; (b) 254 km
