At 5 a.m., Ivan and Gabriel left Park M and drove towards Park N at average speeds of 94 km/h and 57 km/h respectively. Upon reaching Park N, Ivan rested for 3 hours. He then headed back for Park M at an average speed of 94 km/h along the same route. Ivan and Gabriel met each other on their way at 1 p.m.
- How far had Ivan covered when he met Gabriel on the way?
- How far apart were the two parks?
(a)
Time taken by Gabriel = 8 h
Time taken by Ivan = 8 - 3 = 5 h
Distance covered by Ivan when he met Gabriel
= 5 x 94
= 470 km
(b)
Distance travelled by Gabriel
= 8 x 57
= 456 km
Distance of the two parks
= (470 + 456) ÷ 2
= 926 ÷ 2
= 463 km
Answer(s): (a) 470 km; (b) 463 km
