in time taken to travel between two cities​

Answer 1

Answer:

A new bridge between two cities reduced the travel time from 40 minutes to 10 minutes.Find the decrease percentage of travel time.​

Step-by-step explanation:

The original travel time between the two cities = 40 minutes

Due to the new bridge, the reduced travel time between the two cities = 10 minutes

∴ The difference between the travel time is,

= 40 minutes - 10 minutes

= 30 minutes

Now,

The decrease percentage of travel time is given as,

=  

=  

=  

=  

=  

Thus, the decrease percentage of travel time is → 75%.
