With a uniform speed a car covers the distance in 8 hours. Had the speed been increased by 5 km/hr, the same distance could have been covered in 7 1/2 hours. What is the distance covered?	Choose one:
A) 187 km	B) 480 km	C) 278 km	D) 297 km	E) 600 km
Let the distance be x km. Then,   x/(7 1/2) - x/8 = 5   2x/15 - x/8 = 5 =&gt; x = 600 km.   Answer:600 km
