At 7 a.m., Valen and Ethan left Park C and drove towards Park D at average speeds of 86 km/h and 62 km/h respectively. Upon reaching Park D, Valen rested for 2 hours. He then headed back for Park C at an average speed of 86 km/h along the same route. Valen and Ethan met each other on their way at 1 p.m.
- How far had Valen covered when he met Ethan on the way?
- How far apart were the two parks?
(a)
Time taken by Ethan = 6 h
Time taken by Valen = 6 - 2 = 4 h
Distance covered by Valen when he met Ethan
= 4 x 86
= 344 km
(b)
Distance travelled by Ethan
= 6 x 62
= 372 km
Distance of the two parks
= (344 + 372) ÷ 2
= 716 ÷ 2
= 358 km
Answer(s): (a) 344 km; (b) 358 km
