Question

Alex is driving at constant velocity of 30 mph. How far does he travel in 2.5 hours?

Answer 1

Answer:

${\boxed {\boxed{ \sf 75 \ miles}}$

Explanation:

Distance is the product of speed and time.

$d=s*t$

The speed is 30 miles per hour and the time is 2.5 hours.

$s= 30 \ mi /hr \\t= 2.5 \ hr$

Substitute the values into the formula.

$d= 30 \ mi/hr * 2.5 \ hr$

Multiply and the hours will cancel.

$d= 75 \ mi$

The distance traveled in 2.5 hours is 75 miles.

Answer 2

Answer: 75 miles

Explanation: Since he is driving 30 mph. You multiply how many hours he traveled. 30 x 2 hours = 60. Since he also drove half an hour you divide 30 by 2 which equals 15. So 60 + 15 = 75.
