At 7 a.m., Sean and Jack left Park N and drove towards Park P at average speeds of 95 km/h and 56 km/h respectively. Upon reaching Park P, Sean rested for 2 hours. He then headed back for Park N at an average speed of 95 km/h along the same route. Sean and Jack met each other on their way at 1 p.m.
- How far had Sean covered when he met Jack on the way?
- How far apart were the two parks?
(a)
Time taken by Jack = 6 h
Time taken by Sean = 6 - 2 = 4 h
Distance covered by Sean when he met Jack
= 4 x 95
= 380 km
(b)
Distance travelled by Jack
= 6 x 56
= 336 km
Distance of the two parks
= (380 + 336) ÷ 2
= 716 ÷ 2
= 358 km
Answer(s): (a) 380 km; (b) 358 km
