At 7 a.m., Howard and Japheth left Park C and drove towards Park D at average speeds of 70 km/h and 50 km/h respectively. Upon reaching Park D, Howard rested for 2 hours. He then headed back for Park C at an average speed of 70 km/h along the same route. Howard and Japheth met each other on their way at 12 noon.
- How far had Howard covered when he met Japheth on the way?
- How far apart were the two parks?
(a)
Time taken by Japheth = 5 h
Time taken by Howard = 5 - 2 = 3 h
Distance covered by Howard when he met Japheth
= 3 x 70
= 210 km
(b)
Distance travelled by Japheth
= 5 x 50
= 250 km
Distance of the two parks
= (210 + 250) ÷ 2
= 460 ÷ 2
= 230 km
Answer(s): (a) 210 km; (b) 230 km
