A person can travel at the speed of 40 miles per hour. If the speed is increased by '50%' , how long will it take to cover 330 miles?
Answers
Step-by-step explanation:
A person can travel at the speed of 40 miles per hour. If the speed is increased by 50%, how long will it take to cover 330 miles ? Distance to be covered is 330 miles. If the person is increased by 50%, it will take 5 hrs 30 minutes to cover 330 miles distance.
Given : A person can travel at the speed of 40 miles per hour.
To find : If the speed is increased by '50%' , how long will it take to cover 330 miles?
Solution :
We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the required time)
Initial speed = 40 mph
After getting increased by 50%, the speed becomes :
= [40 + (40 × 50%)] mph
= [40 + (40 × 50/100)] mph
= (40 + 20) mph
= 60 mph
Now,
The person travels 60 miles in = 1 hour
The person travels 1 mile in = 1/60 hour
The person travels 330 miles in = (1 × 330)/60 = 5.5 hours
So, he can travel 330 miles in :
= 5.5 hours
= 5 hours + 0.5 hour
= 5 hours + 30 minutes
= 5 hours 30 minutes
[As, 1 hour = 60 minutes ; 0.5 hour = 30 minutes]
Hence, it will take 5 hours 30 minutes to cover 330 miles.
