At 7 a.m., Bobby and Warren left Park K and drove towards Park L at average speeds of 90 km/h and 62 km/h respectively. Upon reaching Park L, Bobby rested for 2 hours. He then headed back for Park K at an average speed of 90 km/h along the same route. Bobby and Warren met each other on their way at 12 noon.
- How far had Bobby covered when he met Warren on the way?
- How far apart were the two parks?
(a)
Time taken by Warren = 5 h
Time taken by Bobby = 5 - 2 = 3 h
Distance covered by Bobby when he met Warren
= 3 x 90
= 270 km
(b)
Distance travelled by Warren
= 5 x 62
= 310 km
Distance of the two parks
= (270 + 310) ÷ 2
= 580 ÷ 2
= 290 km
Answer(s): (a) 270 km; (b) 290 km
