At 6 a.m., Bobby and Rael left Park D and drove towards Park E at average speeds of 93 km/h and 52 km/h respectively. Upon reaching Park E, Bobby rested for 3 hours. He then headed back for Park D at an average speed of 93 km/h along the same route. Bobby and Rael met each other on their way at 1 p.m.
- How far had Bobby covered when he met Rael on the way?
- How far apart were the two parks?
(a)
Time taken by Rael = 7 h
Time taken by Bobby = 7 - 3 = 4 h
Distance covered by Bobby when he met Rael
= 4 x 93
= 372 km
(b)
Distance travelled by Rael
= 7 x 52
= 364 km
Distance of the two parks
= (372 + 364) ÷ 2
= 736 ÷ 2
= 368 km
Answer(s): (a) 372 km; (b) 368 km
