10 and 40 are the awnsers ten bring that times 4 is 40 plus 10
Answer:
Step-by-step explanation:
((((((.5 mile = .25 hour<<<<<<<<<<<<<<<<<<<<<<<<<<
Multiply both sides by 4, because there are 4 quarters in 1 hour
(4)(.5) = (.25)(4)
2 miles =1 hr
Multiply both sides of the original equation by 3 to figure out how far in 3/4 of an hour
(3)(.5) = (3)(.25)
1.5 miles = 3/4 of an hour
now add the two answers together to figure out that the person walked 3.5 miles in 1 3/4 hours
***You also could have multiplied both sides of the original equation by 7, recognizing that that there are 7 quarters in 1.75 hours.
