At 5 a.m., Eric and Jenson left Park P and drove towards Park Q at average speeds of 89 km/h and 51 km/h respectively. Upon reaching Park Q, Eric rested for 2 hours. He then headed back for Park P at an average speed of 89 km/h along the same route. Eric and Jenson met each other on their way at 12 noon.
- How far had Eric covered when he met Jenson on the way?
- How far apart were the two parks?
(a)
Time taken by Jenson = 7 h
Time taken by Eric = 7 - 2 = 5 h
Distance covered by Eric when he met Jenson
= 5 x 89
= 445 km
(b)
Distance travelled by Jenson
= 7 x 51
= 357 km
Distance of the two parks
= (445 + 357) ÷ 2
= 802 ÷ 2
= 401 km
Answer(s): (a) 445 km; (b) 401 km
