Atrain makes a trip at 65 mi/h. a plane traveling 130 mi/h makes the same trip in 3 fewer hours. write and solve an equation to find the distance of the trip.

The formula used for calculating the time is:

t = d / v

where t is time, d is distance and v is velocity

We know that the difference in the two times is 3 hours, therefore:

d / 65 – d / 130 = 3

Calculating for d:

d = 30 / (1/65 – 1/130)

d = 3900 miles

hope this !

let me know
