At 6 a.m., Simon and Vaidev left Park Q and drove towards Park R at average speeds of 99 km/h and 61 km/h respectively. Upon reaching Park R, Simon rested for 2 hours. He then headed back for Park Q at an average speed of 99 km/h along the same route. Simon and Vaidev met each other on their way at 12 noon.
- How far had Simon 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 Simon = 6 - 2 = 4 h
Distance covered by Simon when he met Vaidev
= 4 x 99
= 396 km
(b)
Distance travelled by Vaidev
= 6 x 61
= 366 km
Distance of the two parks
= (396 + 366) ÷ 2
= 762 ÷ 2
= 381 km
Answer(s): (a) 396 km; (b) 381 km
