Solution:
For problems involving distance and time we are required to find the speed in hour time frame.
Some important formulas involving distance, time and speed are
distance=speed x time
speed= distance/time
It is given that car travels 441 kilometers in 4 hours
First we need to find the speed of car in kilometer/hour
Therefore, speed of car = distance/time= 441/4= 110.25 kilometer/hour
(from the formula speed=distance/time)
We are required to find the time taken by the car to travel 112 kilometers
Therefore, time taken by car to travel 112 kilometer=112/110.25
=1.01598 hours
(If time required in minutes then we know that 1 hour=60 minutes)
Hence, the car takes 1.0158 hours or 60.95 minutes to cover the distance
