ANSWER:
20%
STEP-BY-STEP EXPLANATION:
Given that when a new bridge is built, the average time taken by a bus to travel from one city to another is reduced from 50 minutes to 40 minutes.
We need to find out the percentage decrease in time taken to travel between two cities.
Now,
The difference between the travel time = The original travel time between the two cities - The reduced travel time between the two cities
= (50 - 40) minutes
= 10 minutes
Now,
The decrease% of travel time = Difference/Time travel × 100
= 10/50 × 100
= 10(2)
= 20
Therefore, the percentage decrease in time taken to travel between two cities is 20%.
Answer:
Original time=50 mins
Reduced time due to the new bridge=40 mins
Difference between the two times=50 mins-40 mins
Decrease percentage of time travel=difference/original time×100
=>10/50×100=20%
