Answer:
b. 200/x
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
First half speed= x
Second half speed= 1.5 x (1.5 times faster on the second 120 miles of his trip)
Since:
Time = distance /speed
Total time = 1st half time + 2nd half time
Replacing with the values given
Total time =120/ x + 120/1.5x
Total time = 180/ 1.5x + 120 /1.5x
Total time = 180+120/1.5x
Total time = 300/1.5x = 200/x

She will need 288 ft of Christmas lights
Step by Step:
First we find how many feet is needed to go around 1 window. We do this by adding up all four of its sides.
4+4+2+2= 12
Because there are 15 windows be multiply the feet needed for 1 window by 15.
12•15=180
Repeat the first two steps for the garage doors to find that she needs 108ft of lights for 3 garage doors and add the feet needed for the windows to the feet needed for the garages
180+108=288
