At 5 a.m., Daniel and Andy left Park W and drove towards Park X at average speeds of 77 km/h and 50 km/h respectively. Upon reaching Park X, Daniel rested for 2 hours. He then headed back for Park W at an average speed of 77 km/h along the same route. Daniel and Andy met each other on their way at 1 p.m.
- How far had Daniel covered when he met Andy on the way?
- How far apart were the two parks?
(a)
Time taken by Andy = 8 h
Time taken by Daniel = 8 - 2 = 6 h
Distance covered by Daniel when he met Andy
= 6 x 77
= 462 km
(b)
Distance travelled by Andy
= 8 x 50
= 400 km
Distance of the two parks
= (462 + 400) ÷ 2
= 862 ÷ 2
= 431 km
Answer(s): (a) 462 km; (b) 431 km
