At 7 a.m., Michael and Jeremy left Park C and drove towards Park D at average speeds of 72 km/h and 54 km/h respectively. Upon reaching Park D, Michael rested for 2 hours. He then headed back for Park C at an average speed of 72 km/h along the same route. Michael and Jeremy met each other on their way at 2 p.m.
- How far had Michael covered when he met Jeremy on the way?
- How far apart were the two parks?
(a)
Time taken by Jeremy = 7 h
Time taken by Michael = 7 - 2 = 5 h
Distance covered by Michael when he met Jeremy
= 5 x 72
= 360 km
(b)
Distance travelled by Jeremy
= 7 x 54
= 378 km
Distance of the two parks
= (360 + 378) ÷ 2
= 738 ÷ 2
= 369 km
Answer(s): (a) 360 km; (b) 369 km
