r = 60 m/h t = 2 h D = r t = (60m/h) x (2h) = 120 mi
Rate. The official equation is r=d/t, or rate=distance divided by time. Example: A train is traveling about 450 miles to Spain. It gets there in 5 hours. Set up your equation: r=d/t r=450/5 r=90 which means that the train was traveling at a rate/speed of 90 miles per hour. If you are unsure of the answer just plug it in and check it. 90=450/5 90=90 True Now you have verified your equation, and the answer is that the train was traveling 90 mph.
The circumference of a circle is 2 * r * pi or d * pi; the diameter "d" = 2* the radius "r". "pi" is - VERY approximately! - 3.14. The area of a circle is pi * r^2. There is a calculator built into Windows, or you can use the calculator built into Google.

90 degrees on a right angle.
d=r/t (D equals r divided on t
Distance equals rate times time. d=r*t, so t=d/r. Solving for t: t=500/90=5.55 hours, or about 5:33.
d = r t t = d / r
im not sure hahaha
r+d/t
90% R&D is used for the quality increase from 90% to 100%.
C = pi*r82 C = Pi*r*2 90=R Thus 180*Pi
