Question

3

A car travels at an average speed of 60 km/h for 15 minutes.
How far does the car travel in 15 minutes?
D
900 km
C 240 km
4.0 km
A
В B 15 km

Answer 1

(Option B)The car travels 15km in 15 minutes.

Step-by-step explanation:

Notice that the speed is written using units of km/h and the time is written using units of minutes.

Convert the time interval to hours. Remember that 1 hour equals 60 minutes:

15 min = 15 min ×
`(1h)/(60~min)=0.25h`

The distance d that a particle travels during a time t if it moves at an average speed v is given by the formula:

d = v · t

Replace v=60km/h and t=0.25h to find the distance traveled by car:

`d=(60(km)/(h)) ~x~(0.25h)=15km`

Therefore, the car travels 15km in 15 minutes.

Hope this helps!
