How did I travel if I went from nyc to Trenton a distance of 90 miles at 45 miles per hour how long did it take me

Answer: 2 hours

Mathematical Equation for this problem:

45x = 90

x = 2 Divide each side by 45.

Final Answer: 2 hours

Here, we must set up a proportion.

90/x = 45/1

Now, cross multiply.

90*1 = 45*x Multiply each

90 = 45x Our result.

Now, divide 45 by both sides to isolate the variable.

45x/45 = 90/45 Divide by both sides.

x = 90/45 Now divide

x = 2 x equals 2

Now that we know that x equals two, we also know how long it took him to drive. Add units to our answer.

Final answer: It took us 2 hours
