how long will it take you to drive 120 miles at a speed of 15 miles per hour?

Question

pls help me im in 6th almost done getting ready for 7th grade and i cant do this alone

Answer 1

Since distance equals speed times time (d = st), we have

 

t = d/s

 

where  d = 120 miles  and s = 15 miles per hour

t = d / s

t = 120 / 15

t = 8

 

It will take 8 hours to drive 120 miles at a speed of 15 miles per hour.

Answer 2

Hi Mia,

 

If you drive 15 mi per hour, you will be covering 15 miles each other you travel.

 

If you know the total distance traveled, then you can simply divide it by speed to get the time it takes to cover that distance. 

 

In this case distance =20 mi

speed = 15mi/hr

time = distace/speed

=120/15

=8 hours

Answer 3

Use the formula; distance = average speed * time taken, or d = v * t

 

from the above formula and rearranging the quantities we get;  time taken = distance/average speed

 

time taken = 120 miles/15 miles per hour   = 8 hours
