At 7 a.m., George and Rael left Park Z and drove towards Park A at average speeds of 72 km/h and 56 km/h respectively. Upon reaching Park A, George rested for 3 hours. He then headed back for Park Z at an average speed of 72 km/h along the same route. George and Rael met each other on their way at 2 p.m.
- How far had George covered when he met Rael on the way?
- How far apart were the two parks?
(a)
Time taken by Rael = 7 h
Time taken by George = 7 - 3 = 4 h
Distance covered by George when he met Rael
= 4 x 72
= 288 km
(b)
Distance travelled by Rael
= 7 x 56
= 392 km
Distance of the two parks
= (288 + 392) ÷ 2
= 680 ÷ 2
= 340 km
Answer(s): (a) 288 km; (b) 340 km
