Sure, I can help you set up and solve these problems. Let's start with problem #3.
Problem #3:
To find the distance covered by the convoy in kilometers after 3.7 hours, we need to convert the speed limit from miles per hour (MPH) to kilometers per hour (KPH) and then multiply it by the time traveled.
1. Convert the speed limit from MPH to KPH:
1 mile = 1.61 kilometers (approximately)
35 MPH * 1.61 = 56.35 KPH (approximately)
2. Multiply the converted speed by the time traveled:
56.35 KPH * 3.7 hours = 208.895 kilometers (approximately)
Therefore, the convoy will cover approximately 208.895 kilometers after 3.7 hours on the road traveling at the posted speed limit.
Now, let's move on to problem #5.
Problem #5:
The formula to determine the volume for a cubic foot is slightly different from the formula you provided.
The correct formula to determine the volume for a cubic foot (V) is:
V = (L)(W)(H)
There is no need to multiply by 12 inches in this case.
I hope this clarifies how to set up and solve the given problems. Let me know if you have any further questions!
