At 5 a.m., Daniel and Howard left Park U and drove towards Park V at average speeds of 76 km/h and 62 km/h respectively. Upon reaching Park V, Daniel rested for 2 hours. He then headed back for Park U at an average speed of 76 km/h along the same route. Daniel and Howard met each other on their way at 2 p.m.
- How far had Daniel covered when he met Howard on the way?
- How far apart were the two parks?
(a)
Time taken by Howard = 9 h
Time taken by Daniel = 9 - 2 = 7 h
Distance covered by Daniel when he met Howard
= 7 x 76
= 532 km
(b)
Distance travelled by Howard
= 9 x 62
= 558 km
Distance of the two parks
= (532 + 558) ÷ 2
= 1090 ÷ 2
= 545 km
Answer(s): (a) 532 km; (b) 545 km
