At 6 a.m., Tom and Carl left Park L and drove towards Park M at average speeds of 92 km/h and 57 km/h respectively. Upon reaching Park M, Tom rested for 2 hours. He then headed back for Park L at an average speed of 92 km/h along the same route. Tom and Carl met each other on their way at 12 noon.
- How far had Tom 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 Tom = 6 - 2 = 4 h
Distance covered by Tom when he met Carl
= 4 x 92
= 368 km
(b)
Distance travelled by Carl
= 6 x 57
= 342 km
Distance of the two parks
= (368 + 342) ÷ 2
= 710 ÷ 2
= 355 km
Answer(s): (a) 368 km; (b) 355 km
