At 9 a.m., Valen and Ryan left Park E and drove towards Park F at average speeds of 84 km/h and 50 km/h respectively. Upon reaching Park F, Valen rested for 2 hours. He then headed back for Park E at an average speed of 84 km/h along the same route. Valen and Ryan met each other on their way at 2 p.m.
- How far had Valen 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 Valen = 5 - 2 = 3 h
Distance covered by Valen when he met Ryan
= 3 x 84
= 252 km
(b)
Distance travelled by Ryan
= 5 x 50
= 250 km
Distance of the two parks
= (252 + 250) ÷ 2
= 502 ÷ 2
= 251 km
Answer(s): (a) 252 km; (b) 251 km
