A car travels at a constant speed of 60 miles per hour. The distance traveled (d) in miles and the time (t) in hours can be represented by the equation: A. d = 60t B. t = 60d C. d = t + 60 D. t = d + 60 相关知识点: ...
If you wish to find miles per hour based on knots then you multiply. In this case,miles per hour = knots × 1.15077945. So if you’re travelling at 16 knots then the equation is 16 x 1.15077945 16 x 1.15077945 = 18.41247 miles per hour If you wish to calculate knots based on miles ...
60 seconds = 1 minute 60 minutes = 1 hour We can now set up the equation using these relationships so theunits cancel outleaving only the desired miles/hour. speedMPH= 2.998 x 108m/sec x (1 km/1000 m) x (0.621 mi/1 km) x (60 sec/1 min) x (60 min/1 hr) Note all the un...
We can find a similar equation for Han,who drove D+70 miles at a rate of R+5, for T+1 hours, giving us D+70=(R+5)(T+1). We can do the same for Jan, giving us D+x=(R+10)(T+2), where x is how much further Jan traveled than lan. We now have three equations:D=RT...
E(A)20(B)24(C)25(D) 26(E)27 相关知识点: 试题来源: 解析 EThis is a d=st problem, so let x be the time it takes to meet. We can write the following equation:12x+18x=45Solving gives us x=1.5. The 18x is Alicia so 18*1.5=(E)27 反馈 收藏 ...
For kinematic equation problems, what do you do if the unit for acceleration is ''g'', and how do you use deceleration for the equation? How many hydrogen atoms, which measure 0.1 nm across, will fit across a single caesium atom with a diameter o...
100K Distance is the measure in a straight line of how far something has traveled, and can be used to calculate speed when time is also known. Learn the equation used to calculate average speed through a set of p...
We can set up an algebraic equation for this problem. From what’s given, we have that 100c+10b+a=55x+100a+10b+c This simplifies to be 0=55x+99a−99c⇒−55x=99a−99c Factoring, we get that −55x=99(a−c)⇒x=−9(a−c)5 Hence, notice that we want a−c...
