At 5 a.m., Tim and Bobby left Park B and drove towards Park C at average speeds of 70 km/h and 52 km/h respectively. Upon reaching Park C, Tim rested for 3 hours. He then headed back for Park B at an average speed of 70 km/h along the same route. Tim and Bobby met each other on their way at 12 noon.
- How far had Tim covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 7 h
Time taken by Tim = 7 - 3 = 4 h
Distance covered by Tim when he met Bobby
= 4 x 70
= 280 km
(b)
Distance travelled by Bobby
= 7 x 52
= 364 km
Distance of the two parks
= (280 + 364) ÷ 2
= 644 ÷ 2
= 322 km
Answer(s): (a) 280 km; (b) 322 km
