If a car travels at a speed of 25 mi/h for t hours, then travels 45mi/h for m hours, what does the expression 25t+45mi represent

V = s/t ⇒ s = vt

25 mi/h · th + 45 mi/h · mh = 25mi · t + 45mi · m = (25t + 45m) mi

Answer: The expression represent the distance that car traveled.

Answer: The expression represent the distance that car traveled.

Velocity = Speed/Time meaning that Speed = Velocity x Time

(25 miles per hour x t hours) + (45 miles per hour x m hours) = 25 miles x t + 45 miles x m = (25t + 45m) miles

(25t + 45m) miles

The expression above represents the distance that the car travelled.
