A truck has traveled 75 miles in 1.5 hours of driving. At the same speed, which proportion can be used to determine how long T (in hours) it would take the truck to travel 325 miles?
Can someone please help walk me through this? I don't understand, but if I ask my teacher she might get upset, because I should know this...
Mr. Porter's grocery bill is $143.74. If 5.3% sales tax is added to the bill, what is the total Mr. Porter owes?
I really need help, My teacher does not explain things good enough and i'm veyr scared i might fail :(
what does 325 /50 =
75/1.5 = 50 mph
325/50 = ?
thank you so much
I just realized I never answered. :/
6.5
Of course, I'd be happy to help you with this problem! Let's break it down step by step.
To solve this question, we can set up a proportion to find the unknown variable, which is the time it would take the truck to travel 325 miles.
First, let's write down what we know:
Distance traveled: 75 miles
Time taken: 1.5 hours
We can express this information in the form of a fraction (distance divided by time):
75 miles / 1.5 hours
Next, we set up the proportion. Since we're trying to find the time it takes to travel 325 miles, we use a variable T to represent the unknown time:
75 miles / 1.5 hours = 325 miles / T hours
Now, we can cross-multiply and solve the equation:
75 miles * T hours = 1.5 hours * 325 miles
To solve for T (the unknown time), divide both sides of the equation by 75 miles:
T hours = (1.5 hours * 325 miles) / 75 miles
Now, we can simplify the expression:
T hours = 4.875 hours
Therefore, the proportion that can be used to determine how long T, in hours, it would take the truck to travel 325 miles is:
75/1.5 = 325/T
