Answer:
TRY 416in²
Step-by-step explanation:
front:
8×17=136÷2=68
same for the back
back = 68
side 1=
7×15=105
side 2=
8×7=56
bottom=
17×7=119
68+68+105+56+119=416
-60x^3 + 480, that’s what I got
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.
