substitute to find the value of the expression.
A train must cover a distance of 2398 miles. The velocity, in miles per hour, of the train is where t is the time,in hours, to complete the trip. If the train completes the trip in 22 hours what is it's velocity? A) 109 miles per hours B) 104 miles per hour C) .01 miles per hour D0 52,756 miles per hour.
thank you for any help.
Distance = 2398 miles
Time = 22 hours
Velocity = distance / time
= 2398 / 22 mph
To find the velocity of the train, we need to substitute the value of t, which is the time taken to complete the trip, into the expression for velocity.
The expression for velocity is: velocity = distance / time.
Given that the distance the train needs to cover is 2398 miles and the time taken to complete the trip is 22 hours, we can substitute these values into the expression.
velocity = 2398 miles / 22 hours
Now, performing the division:
velocity = 109.0 miles per hour
Therefore, the velocity of the train, when completing the trip in 22 hours, is 109 miles per hour.
So, the correct option is A) 109 miles per hour.
