At 9 a.m., Ivan and Neave left Park Q and drove towards Park R at average speeds of 97 km/h and 57 km/h respectively. Upon reaching Park R, Ivan rested for 2 hours. He then headed back for Park Q at an average speed of 97 km/h along the same route. Ivan and Neave met each other on their way at 1 p.m.
- How far had Ivan covered when he met Neave on the way?
- How far apart were the two parks?
(a)
Time taken by Neave = 4 h
Time taken by Ivan = 4 - 2 = 2 h
Distance covered by Ivan when he met Neave
= 2 x 97
= 194 km
(b)
Distance travelled by Neave
= 4 x 57
= 228 km
Distance of the two parks
= (194 + 228) ÷ 2
= 422 ÷ 2
= 211 km
Answer(s): (a) 194 km; (b) 211 km
