At 6 a.m., Albert and Rael left Park E and drove towards Park F at average speeds of 72 km/h and 53 km/h respectively. Upon reaching Park F, Albert rested for 2 hours. He then headed back for Park E at an average speed of 72 km/h along the same route. Albert and Rael met each other on their way at 2 p.m.
- How far had Albert covered when he met Rael on the way?
- How far apart were the two parks?
(a)
Time taken by Rael = 8 h
Time taken by Albert = 8 - 2 = 6 h
Distance covered by Albert when he met Rael
= 6 x 72
= 432 km
(b)
Distance travelled by Rael
= 8 x 53
= 424 km
Distance of the two parks
= (432 + 424) ÷ 2
= 856 ÷ 2
= 428 km
Answer(s): (a) 432 km; (b) 428 km
