miles per hour/

Answer 1

Answer:

miles per hour = 3

Step-by-step explanation:

We have to find speed in miles per hour

formula for speed = distance /time

distance = 3/4 miles

time = 15 minutes

we have to convert time in hours

60 minutes = 1 hour

15 minutes = 1/60 * 15 = 1/4 hours

hours = 1/4

now speed = distance/time = 3/4 miles / 1/4 hours = 3 miles/ hour

miles per hour = 3

for table given values can be used

using time and miles rows

time  =1/4 hour

miles = 3/4

time  =2*1/4 hour = 1/2 hour

miles = 2*3/4 = 3/2 miles

time  =3*1/4 hour = 3/2 hour

miles = 3*3/4 = 9/4 hour

time  =4*1/4 hour = 1 hour

miles = 4*3/4 = 3 miles

thus, in 1 hour 3 miles is traveled and

miles per hour = 3
