To solve this, you do:
110 divided by 5 1/2.
If you want your answer in fraction form, you do:
110/1 ÷ 11/2 (the improper fraction form)
To multiply, flip the second fraction to change from dividing to mutiplying:
110/1 × 2/11
Multiply across
110 × 2 = 220 and 1 × 11 = 11
220/11
Simplify:
220 ÷ 11 = 20
Tom babysat for 20 hours.
First you need to find the rate. This problem is based on the formula d = rt
d = distance
r = rate
t = time.
The question is asking how many miles will it travel in 8 hours so to find this out we need to find the rate when the car travels 240 miles in 4 hours. We use this information and plug it into the model d = rt
d = 240
r = don't know yet
t = 4 hr
d = rt
240 = 4r
240 / 4 = 4r / 4
60 = r
r = 60
So the car is going at a rate of 60 miles per hour. Now that we know this we can solve for how many miles the car will travel in 8 hours.
d = rt
d = r * t
d = 60 * 8
d = 480
So the car will travel 480 miles in 8 hours
Another way to think about this is that you know the car traveled 240 miles in 4 hours and the question is wanting to know how far the car will travel in 8 hours, which would be double the 4 hours so 240 + 240 = 480
12 -1/9d = 17
Subtract 12 from both sides
-1/9d = 5
Multiply both sides by -9:
D = -45
The answer is b. d = -45
0.03 x 40... or its either the other way around like 0.02 x 40 lol
