At 7 a.m., Albert and Elijah left Park J and drove towards Park K at average speeds of 97 km/h and 54 km/h respectively. Upon reaching Park K, Albert rested for 3 hours. He then headed back for Park J at an average speed of 97 km/h along the same route. Albert and Elijah met each other on their way at 12 noon.
- How far had Albert covered when he met Elijah on the way?
- How far apart were the two parks?
(a)
Time taken by Elijah = 5 h
Time taken by Albert = 5 - 3 = 2 h
Distance covered by Albert when he met Elijah
= 2 x 97
= 194 km
(b)
Distance travelled by Elijah
= 5 x 54
= 270 km
Distance of the two parks
= (194 + 270) ÷ 2
= 464 ÷ 2
= 232 km
Answer(s): (a) 194 km; (b) 232 km
