At 6 a.m., Tommy and Fred left Park B and drove towards Park C at average speeds of 77 km/h and 59 km/h respectively. Upon reaching Park C, Tommy rested for 2 hours. He then headed back for Park B at an average speed of 77 km/h along the same route. Tommy and Fred met each other on their way at 1 p.m.
- How far had Tommy covered when he met Fred on the way?
- How far apart were the two parks?
(a)
Time taken by Fred = 7 h
Time taken by Tommy = 7 - 2 = 5 h
Distance covered by Tommy when he met Fred
= 5 x 77
= 385 km
(b)
Distance travelled by Fred
= 7 x 59
= 413 km
Distance of the two parks
= (385 + 413) ÷ 2
= 798 ÷ 2
= 399 km
Answer(s): (a) 385 km; (b) 399 km
