To determine the speed, we will divide the total distance covered by the total time spent traveling.

speed=distance\div timespeed=412.5miles\div7.5hrs

<em>Note that 7 1/2 is just equal to 7.5.</em>

<em />

Divide the numbers above and the answer is:

speed=55miles\text{ }per\text{ }hour

Answer:

Ivan was driving at a constant speed of 55 miles per hour.

What does 5/15 equal
harina [27]
Because 5/15 is not a simplified fraction, seeing that its numerator and denominator both have a common factor, you can simplify it to find an equivalent fraction. To do this, divide 5 from the numerator and denominator and then you would get a result of 1/3.

Find the perimeter RST. Round answer to the nearest tenth<br> Show all the work
kow [346]

Answer:

35.1 units

Step-by-step explanation:

Imagine a right-angled triangle with RS as hypotenuse. The base would be 3 units and the height would be 6 units. By Pythagorus:

RS²=3²+6²

RS=\sqrt{45}≈6.7 units

Imagine a right-angled triangle with RT as hypotenuse. The base would be 9 units and the height would be 12 units. By Pythagorus:

RT²=9²+12²

RT=\sqrt{225} = 15 units

Imagine a right-angled triangle with TS as hypotenuse. The base would be 12 units and the height would be 6 units. By Pythagorus:

TS²=12²+6²

TS=\sqrt{180}≈13.4 units

Perimeter=RS+RT+TS

=6.7+15+13.4

=35.1 units
