At 7 a.m., Albert and Perry left Park X and drove towards Park Y at average speeds of 91 km/h and 58 km/h respectively. Upon reaching Park Y, Albert rested for 3 hours. He then headed back for Park X at an average speed of 91 km/h along the same route. Albert and Perry met each other on their way at 12 noon.
- How far had Albert covered when he met Perry on the way?
- How far apart were the two parks?
(a)
Time taken by Perry = 5 h
Time taken by Albert = 5 - 3 = 2 h
Distance covered by Albert when he met Perry
= 2 x 91
= 182 km
(b)
Distance travelled by Perry
= 5 x 58
= 290 km
Distance of the two parks
= (182 + 290) ÷ 2
= 472 ÷ 2
= 236 km
Answer(s): (a) 182 km; (b) 236 km
