At 7 a.m., Tommy and Wesley left Park Q and drove towards Park R at average speeds of 98 km/h and 55 km/h respectively. Upon reaching Park R, Tommy rested for 2 hours. He then headed back for Park Q at an average speed of 98 km/h along the same route. Tommy and Wesley met each other on their way at 1 p.m.
- How far had Tommy covered when he met Wesley on the way?
- How far apart were the two parks?
(a)
Time taken by Wesley = 6 h
Time taken by Tommy = 6 - 2 = 4 h
Distance covered by Tommy when he met Wesley
= 4 x 98
= 392 km
(b)
Distance travelled by Wesley
= 6 x 55
= 330 km
Distance of the two parks
= (392 + 330) ÷ 2
= 722 ÷ 2
= 361 km
Answer(s): (a) 392 km; (b) 361 km
