At 8 a.m., Liam and Vaidev left Park H and drove towards Park J at average speeds of 98 km/h and 61 km/h respectively. Upon reaching Park J, Liam rested for 2 hours. He then headed back for Park H at an average speed of 98 km/h along the same route. Liam and Vaidev met each other on their way at 2 p.m.
- How far had Liam covered when he met Vaidev on the way?
- How far apart were the two parks?
(a)
Time taken by Vaidev = 6 h
Time taken by Liam = 6 - 2 = 4 h
Distance covered by Liam when he met Vaidev
= 4 x 98
= 392 km
(b)
Distance travelled by Vaidev
= 6 x 61
= 366 km
Distance of the two parks
= (392 + 366) ÷ 2
= 758 ÷ 2
= 379 km
Answer(s): (a) 392 km; (b) 379 km
