At 5 a.m., Ian and Bryan left Park Q and drove towards Park R at average speeds of 74 km/h and 62 km/h respectively. Upon reaching Park R, Ian rested for 2 hours. He then headed back for Park Q at an average speed of 74 km/h along the same route. Ian and Bryan met each other on their way at 12 noon.
- How far had Ian covered when he met Bryan on the way?
- How far apart were the two parks?
(a)
Time taken by Bryan = 7 h
Time taken by Ian = 7 - 2 = 5 h
Distance covered by Ian when he met Bryan
= 5 x 74
= 370 km
(b)
Distance travelled by Bryan
= 7 x 62
= 434 km
Distance of the two parks
= (370 + 434) ÷ 2
= 804 ÷ 2
= 402 km
Answer(s): (a) 370 km; (b) 402 km
