Total distance John drove=450 miles
total time=8 hours
let the number of hours he drove on highway be x, number of hours he drove on turnpike will be (8-x) hours
since
distance=speed*time
distance traveled in highway=50x
distance traveled in turnpike=60(8-x)
thus the total distance will be:
50x+60(8-x)=450
simplifying the above
50x+480-60x=450
-10x=450-480
-10x=-30
thus
x=3 hours
Thus he drove on highway for 3 hours.
1675/3890 you are dividing 1675 by 3890 so it equals 0.43059...=0.4 simplified to the first decimal
Answer:
D
Step-by-step explanation:
irdk sorry if its wrong :(
What you have to do is look at all the measurements (ft) and they are labeled. And some of the sides that aren't labeled have clues of what they could be. So when I added, I got 78 ft for my answer.
