help...please sooo this is the problem 3/4h x 19mi/ 1/4h plsssss help :( I don't understand!
if you can go 19 mi in 1/4 hr , how far can you go in 3 times the time?
you have all the quantities -- just do the multiplications
(3/4 hr) * (19mi)/(1/4 hr) = 3/4 * 19 * 4/1 = 57 mi
Note how the units cancel, just like the numbers: hr * mi/hr = mi
That's why distance = speed * time
Don't worry, I'm here to help you understand this problem. Let's break it down step by step.
The problem is: (3/4h) * (19mi / 1/4h)
To solve this, we can follow these steps:
Step 1: Simplify any fractions involved.
- In this case, 3/4h and 1/4h are both fractions involving hours (h). To simplify, we can cancel out the 'h' in the numerator and denominator of each fraction.
Simplifying 3/4h:
- Cancel out the 'h': 3/4h = 3/4
Simplifying 1/4h:
- Cancel out the 'h': 1/4h = 1/4
Now we can rewrite the problem as: (3/4) * (19mi / 1/4)
Step 2: Multiply the numerators and denominators separately.
- Multiply the numerators: 3 * 19mi = 57mi
- Multiply the denominators: 4 * 1/4 = 1
Now we have: 57mi / 1
Step 3: Simplify the final fraction.
- Divide the numerator by the denominator: 57mi / 1 = 57mi
So, the final answer to the problem is 57 miles (mi).
Let me know if you need any further clarification or assistance with anything!
