At 5 a.m., Valen and Ryan left Park E and drove towards Park F at average speeds of 90 km/h and 58 km/h respectively. Upon reaching Park F, Valen rested for 3 hours. He then headed back for Park E at an average speed of 90 km/h along the same route. Valen and Ryan met each other on their way at 12 noon.
- How far had Valen covered when he met Ryan on the way?
- How far apart were the two parks?
(a)
Time taken by Ryan = 7 h
Time taken by Valen = 7 - 3 = 4 h
Distance covered by Valen when he met Ryan
= 4 x 90
= 360 km
(b)
Distance travelled by Ryan
= 7 x 58
= 406 km
Distance of the two parks
= (360 + 406) ÷ 2
= 766 ÷ 2
= 383 km
Answer(s): (a) 360 km; (b) 383 km
