At 9 a.m., Carl and Bobby left Park T and drove towards Park U at average speeds of 99 km/h and 52 km/h respectively. Upon reaching Park U, Carl rested for 3 hours. He then headed back for Park T at an average speed of 99 km/h along the same route. Carl and Bobby met each other on their way at 2 p.m.
- How far had Carl covered when he met Bobby on the way?
- How far apart were the two parks?
(a)
Time taken by Bobby = 5 h
Time taken by Carl = 5 - 3 = 2 h
Distance covered by Carl when he met Bobby
= 2 x 99
= 198 km
(b)
Distance travelled by Bobby
= 5 x 52
= 260 km
Distance of the two parks
= (198 + 260) ÷ 2
= 458 ÷ 2
= 229 km
Answer(s): (a) 198 km; (b) 229 km
