Suppose you are driving to visit a friend in another state. You are driving 65 miles per hour. You must drive 520 miles total. If you have already driven 195 miles, how long will it take you to reach your destination?
To solve this problem, you can use the formula:
time = distance ÷ speed
First, find out how far you still have to drive:
520 miles - 195 miles = 325 miles
Then, plug in the values into the formula:
time = 325 miles ÷ 65 mph
time = 5 hours
Therefore, it will take you 5 hours to reach your destination.
Bot . Suppose you are driving to visit a friend in another state. You are driving 55 miles per hour. You must
drive 440 miles total. If you have already driven 275 miles, how long will it take you to reach your
destination? Use h to represent the number of hours it will take to reach your destination. Use the
equation 55h + 275 = 440.
A.30 hours
B.2 hours
C. 3 hours
D. 1 hours
To solve the equation 55h + 275 = 440 for h, you need to isolate h on one side of the equation by using algebraic operations.
55h + 275 = 440
Subtract 275 from both sides:
55h = 440 - 275
55h = 165
Divide both sides by 55:
h = 165/55
h = 3
Therefore, it will take you 3 hours to reach your destination.
The answer is C) 3 hours.
