CAT Exam Numerical Ability Time Distance and Speed

During the journey, a car covers x miles for 2 hours, and 200 miles for 3 hours. Find x if the average speed for the entire journey is 70 miles per hour.

Read Solution (Total 1)

x = 150 miles.

Total hours of travel = 3hours + 2hours = 5hours

Average speed of entire journey = 70miles/hour

Therefore, for 5 hours, they travel = 70*5 = 350miles

(200miles + x miles = 350 miles) in (3hours +2hours = 5hrs)
x = 350-200
x = 150miles.
