Answer:
35 mph
Step-by-step explanation:
time = distance / speed
210 miles and has an average of a certain speed
t = 210 / s
If the average speed had been 3mph more, he could have traveled 228 miles in the same length of time
t = 228 / (s + 3)
Set equal
210 / s = 228 / (s + 3)
Cross multiply
210s + 630 = 228s
Subtract 210s from both sides
630 = 18s
Divie both sides by 18
35 = s
35 mph
6n=$8.34, 8.34/6= 1.39 N=1.39
Answer:
150 in^3
Step-by-step explanation:
A= B*h / 2
Base= 10*6 = 60
60*5 = 300
300/2 = 150 in^3
Answer:
Step-by-step explanation:
Mr Thompson wants to protect his garage by installing a flood barrier. He connects 2 barriers side by side. The length of each flood barrier is 9 ft while the height of each barrier is 2 ft. The barriers are rectangular in shape. The area of each rectangular barrier is expressed as length × height.
Therefore
Area of each barrier is 9 × 2 = 18 ft^2
The combined area of the barriers would be
18 × 2 = 36 ft^2
