The question is missing information: " . . . how far would he go in an <u>???"</u>
<u></u>
If the question is how far he would go in a [Pick a despised car model} ? The answer is still 400. The car would break down.
If the question is how far would he go in the same amount of time:
Whe the speed limit was 55, it would take Bob (55 miles/hr)*(X hr) = 400 miles
X = 7.273 hours to go 400 miles at 55 mph.
A speed limit of 70 mph would allow Bob the go:
(70 miles/hour)*(7.272 hours) = 509.1 miles
MISSING DETAILS
Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?
Answer:
Minutes = 8 minutes
Step-by-step explanation:
Topic: Inequality
Given:
Available Size of water = 17 liters
Increment = 5 liters/minute
Size of water needed = At least 57 liters
Putting the above together, as have
17 + 5m > 57
where m represents total minutes and > represent at least
Solving the Inequality
5m > 57 - 17
5m > 40 ------ Divide through by 5
5m/5 > 40/5
m > 8
So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.
