A car travels 100 mph for the first half of a 400 mile race. How fast must the car go to average 200 mph?
solution:
let us first find te time required to complet 400 miles at 200 mp
400miles/200 miles/hour =2hour.
as the 2 hours are already consumed there is no way to achieve an average speed
of 200mph from this point.
