At 6 a.m., Jeremy and Rael left Park E and drove towards Park F at average speeds of 84 km/h and 59 km/h respectively. Upon reaching Park F, Jeremy rested for 3 hours. He then headed back for Park E at an average speed of 84 km/h along the same route. Jeremy and Rael met each other on their way at 12 noon.
- How far had Jeremy covered when he met Rael on the way?
- How far apart were the two parks?
(a)
Time taken by Rael = 6 h
Time taken by Jeremy = 6 - 3 = 3 h
Distance covered by Jeremy when he met Rael
= 3 x 84
= 252 km
(b)
Distance travelled by Rael
= 6 x 59
= 354 km
Distance of the two parks
= (252 + 354) ÷ 2
= 606 ÷ 2
= 303 km
Answer(s): (a) 252 km; (b) 303 km
