At 5 a.m., Howard and Bobby left Park N and drove towards Park P at average speeds of 77 km/h and 56 km/h respectively. Upon reaching Park P, Howard rested for 3 hours. He then headed back for Park N at an average speed of 77 km/h along the same route. Howard and Bobby met each other on their way at 12 noon.
- How far had Howard covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 7 h
Time taken by Howard = 7 - 3 = 4 h
Distance covered by Howard when he met Bobby
= 4 x 77
= 308 km
(b)
Distance travelled by Bobby
= 7 x 56
= 392 km
Distance of the two parks
= (308 + 392) ÷ 2
= 700 ÷ 2
= 350 km
Answer(s): (a) 308 km; (b) 350 km
