At 7 a.m., Jeremy and Ryan left Park E and drove towards Park F at average speeds of 93 km/h and 56 km/h respectively. Upon reaching Park F, Jeremy rested for 3 hours. He then headed back for Park E at an average speed of 93 km/h along the same route. Jeremy and Ryan met each other on their way at 12 noon.
- How far had Jeremy covered when he met Ryan on the way?
- How far apart were the two parks?
(a)
Time taken by Ryan = 5 h
Time taken by Jeremy = 5 - 3 = 2 h
Distance covered by Jeremy when he met Ryan
= 2 x 93
= 186 km
(b)
Distance travelled by Ryan
= 5 x 56
= 280 km
Distance of the two parks
= (186 + 280) ÷ 2
= 466 ÷ 2
= 233 km
Answer(s): (a) 186 km; (b) 233 km
