At 7 a.m., Rael and Tim left Park S and drove towards Park T at average speeds of 98 km/h and 50 km/h respectively. Upon reaching Park T, Rael rested for 3 hours. He then headed back for Park S at an average speed of 98 km/h along the same route. Rael and Tim met each other on their way at 12 noon.
- How far had Rael covered when he met Tim on the way?
- How far apart were the two parks?
(a)
Time taken by Tim = 5 h
Time taken by Rael = 5 - 3 = 2 h
Distance covered by Rael when he met Tim
= 2 x 98
= 196 km
(b)
Distance travelled by Tim
= 5 x 50
= 250 km
Distance of the two parks
= (196 + 250) ÷ 2
= 446 ÷ 2
= 223 km
Answer(s): (a) 196 km; (b) 223 km
