At 9 a.m., Ivan and Japheth left Park Q and drove towards Park R at average speeds of 74 km/h and 59 km/h respectively. Upon reaching Park R, Ivan rested for 2 hours. He then headed back for Park Q at an average speed of 74 km/h along the same route. Ivan and Japheth met each other on their way at 1 p.m.
- How far had Ivan covered when he met Japheth on the way?
- How far apart were the two parks?
(a)
Time taken by Japheth = 4 h
Time taken by Ivan = 4 - 2 = 2 h
Distance covered by Ivan when he met Japheth
= 2 x 74
= 148 km
(b)
Distance travelled by Japheth
= 4 x 59
= 236 km
Distance of the two parks
= (148 + 236) ÷ 2
= 384 ÷ 2
= 192 km
Answer(s): (a) 148 km; (b) 192 km
