At 6 a.m., Bobby and Carl left Park K and drove towards Park L at average speeds of 92 km/h and 50 km/h respectively. Upon reaching Park L, Bobby rested for 3 hours. He then headed back for Park K at an average speed of 92 km/h along the same route. Bobby and Carl met each other on their way at 12 noon.
- How far had Bobby covered when he met Carl on the way?
- How far apart were the two parks?
(a)
Time taken by Carl = 6 h
Time taken by Bobby = 6 - 3 = 3 h
Distance covered by Bobby when he met Carl
= 3 x 92
= 276 km
(b)
Distance travelled by Carl
= 6 x 50
= 300 km
Distance of the two parks
= (276 + 300) ÷ 2
= 576 ÷ 2
= 288 km
Answer(s): (a) 276 km; (b) 288 km
