0 0 votes On a $20$ km tunnel connecting two cities A and B there are three gutters. The distance between gutter $1$ and $2$ is half the distance between gutter and $2$ and $3.$ The distance from city A to its nearest gutter, gutter $1$ is equal to the distance of city B from gutter $3.$ On a particular day the hospital in city A receives information that an accident has happened at the third gutter. The victim can be saved only if an operation is started within $40$ minutes. An ambulance started from city A at $30$ km/hr and crossed the first gutter after $5$ minutes. If the driver had doubled the speed after that, what is the maximum amount of time the doctor would get to attend the patient at the hospital? Assume $1$ minutes is elapsed for taking the patient into and out of the ambulance. $4$ minutes $2.5$ minutes $1.5$ minutes Patient died before reaching the hospital Quantitative Aptitude cat2002 quantitative-aptitude time-and-distance + – go_editor 14.2k points 1.3k views answer comment Share Follow Print 0 reply Please log in or register to add a comment.
