At 6 a.m., Julian and Ryan left Park C and drove towards Park D at average speeds of 97 km/h and 61 km/h respectively. Upon reaching Park D, Julian rested for 2 hours. He then headed back for Park C at an average speed of 97 km/h along the same route. Julian and Ryan met each other on their way at 12 noon.
- How far had Julian covered when he met Ryan on the way?
- How far apart were the two parks?
(a)
Time taken by Ryan = 6 h
Time taken by Julian = 6 - 2 = 4 h
Distance covered by Julian when he met Ryan
= 4 x 97
= 388 km
(b)
Distance travelled by Ryan
= 6 x 61
= 366 km
Distance of the two parks
= (388 + 366) ÷ 2
= 754 ÷ 2
= 377 km
Answer(s): (a) 388 km; (b) 377 km
