Answer / guest
75 miles per hour
While going to the destination, the vehicle travels 10 mils
at the speed of 50 miles per hour. So the time taken to
travel 10 miles is
= (60 * 10) / 50
= 12 minutes
Now it's given that round-trip travel time is 20 minutes. So
the vehicle should complete its return trip of 10 miles in 8
minutes. So the speed of the vehicle must
= (60 * 10) / 8
= 75 miles per hour

On the shelf you have 10 identical bottles of identical pills (let?s say there?s a hundred pills in each bottle). However, one of those 10 bottles contains cheap knockoff pills. The only way to differentiate fake pills from real pills is the weight - while real pills weigh 1 g each, the knockoff pills are only 0.9 g. You have one scale that shows the exact weight (down to the mg) of whatever is weighed. How can you tell which bottle contains fake pills with just 1 weighing?
