5. 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.
