At 6 a.m., Daniel and Ahmad left Park R and drove towards Park S at average speeds of 85 km/h and 58 km/h respectively. Upon reaching Park S, Daniel rested for 2 hours. He then headed back for Park R at an average speed of 85 km/h along the same route. Daniel and Ahmad met each other on their way at 2 p.m.
- How far had Daniel covered when he met Ahmad on the way?
- How far apart were the two parks?
(a)
Time taken by Ahmad = 8 h
Time taken by Daniel = 8 - 2 = 6 h
Distance covered by Daniel when he met Ahmad
= 6 x 85
= 510 km
(b)
Distance travelled by Ahmad
= 8 x 58
= 464 km
Distance of the two parks
= (510 + 464) ÷ 2
= 974 ÷ 2
= 487 km
Answer(s): (a) 510 km; (b) 487 km
