At 7 a.m., Ivan and Dylan left Park U and drove towards Park V at average speeds of 83 km/h and 56 km/h respectively. Upon reaching Park V, Ivan rested for 2 hours. He then headed back for Park U at an average speed of 83 km/h along the same route. Ivan and Dylan met each other on their way at 1 p.m.
- How far had Ivan covered when he met Dylan on the way?
- How far apart were the two parks?
(a)
Time taken by Dylan = 6 h
Time taken by Ivan = 6 - 2 = 4 h
Distance covered by Ivan when he met Dylan
= 4 x 83
= 332 km
(b)
Distance travelled by Dylan
= 6 x 56
= 336 km
Distance of the two parks
= (332 + 336) ÷ 2
= 668 ÷ 2
= 334 km
Answer(s): (a) 332 km; (b) 334 km
