At 7 a.m., Daniel and Ivan left Park H and drove towards Park J at average speeds of 90 km/h and 64 km/h respectively. Upon reaching Park J, Daniel rested for 2 hours. He then headed back for Park H at an average speed of 90 km/h along the same route. Daniel and Ivan met each other on their way at 12 noon.
- How far had Daniel covered when he met Ivan on the way?
- How far apart were the two parks?
(a)
Time taken by Ivan = 5 h
Time taken by Daniel = 5 - 2 = 3 h
Distance covered by Daniel when he met Ivan
= 3 x 90
= 270 km
(b)
Distance travelled by Ivan
= 5 x 64
= 320 km
Distance of the two parks
= (270 + 320) ÷ 2
= 590 ÷ 2
= 295 km
Answer(s): (a) 270 km; (b) 295 km
