30KM TRAVEL IN 25 MINUTES

Step-by-step explanation:

1 HOUR IS 60 MINUTES

$\bf72 × \frac{25 }{60}$

So, solution is 30km per minutes.

Answer 2

Answer:

30 km

Explanation:

To find the distance d covered by the car moving at 72 km/hr. in 25 minutes, we need to use the familiar "distance-rate-time" formula:

d = rt, where r is the constant rate of travel or the average rate of travel of the car and t is the time traveled.

It's given that r = 72 km/hr and the time t = 25 min.

Before, substituting the given information into the distance-rate-time formula, we need to convert the given time t = 25 minutes to hours as follows:

25 min. = 25 min.(1)

= 25 min. (1 hr./60 min.) min. since there are 60 minutes in 1 hour.

= (25 min./60 min.)(1 hr.)

= (25/60) hr. (Note: the "minute" units cancelled out)

= (5/12) hr.

Now, substituting into the "distance-rate-time" formula for time t and for speed r to find distance d traveled, we have:

d = rt

= (72 km/hr.)[(5/12) hr.]

= (6)(5) km.

d = 30 km. is the distance covered by a car travelling at a constant speed or an average speed of 72 km/hr. in 25 minutes.
