Given : A truck covers a particular distance in 3 hours with the speed of 60 miles per hour.
The speed is increased by 30 miles per hour,
To find : the time taken by the truck to cover the same distance.
Solution:
Distance = Speed * Time
Speed = 60 miles / hr
Time = 3 hrs
Distance = 60 * 3 = 180 miles
New Speed = 60 + 30 = 90 miles/hr
New time taken = 180/90 = 2 hrs
the time taken by the truck to cover the same distance is 2 hrs
