These are very easy to set up with a "chart" ---------Distance-----Rate---Time (D=RxT) slow way --6x----------x-------6 fast way - 5(x+7)-----x+7------5 so 6x = 5(x+7) 6x=5x+35+ x=35 The speed on the slower trip was 35 mph, and on the return trip 42 mph A consultant traveled 6...

distance = rate * time height = 5.2 * 340 = 1768m It should be as simple as that.

distance = rate*time solve for distance. rate = 65 miles/hour time = 2 sec. change 2 sec to hours first and the answer will come out in miles. Convert that to feet, then to meters. Post your work if you get stuck. I don't have my calculator handy but I think the distance in ...

Isn't this just distance = rate*time? 2000 = 20*time , solve for time, t = 2000/20 = 100 seconds is how long it took the torpedo to get to the target. It took 101.4 seconds after the torpedo was fired to hear the sound and 100 seconds was required for the torpedo to make the ...

distance = rate*time time for first hallway is time = distance/rate = 35.0/3.50 = ?? Do time for second hallway and third hallway the same, add the times together, and see if the total adds to more than 1 minute (the difference between 10:29 and 10:30).

distance = rate*time d= 325 x 4 = 1,300 miles. If flying into a 25 mph head wind, then the speed is just 325-25 = 300. Plug in d and r and calculate time.

Use the equation distance = rate * time. Don't forget to convert everything to the same units.

On Monday, Voltaire drove to town at 60 miles per hour. On Tuesday, he drove to town at 40 miles per hour. If the totaling traveling time for both trips was 15 hours, how far was it to town? I know distance=(rate)(time).so I set it up like this...x=distance X/(60)(15) + x/(40...

The last equation.... distance= rate/time. You need the average velocity, not the initial. Average here is 1/2 the initial.

You are on the right track. Your conversion to m/s looks good. The question is how far does the car move in 0.71s. distance = rate*time = 16.111m/s * 0.71s =11.44m

distance/rate=time 60km/(Javier+6)=42km/Javier 60km*J= 42km*J+6*42km 18J=6*42km Javier speed= 14Km/hr

distance = rate * time so, since the distance covered is the same both ways, .8r * (t+10) = rt .8rt + 8r = rt 8r = .2rt 8 = .2t t = 40 so, total time = 40+10 + 40 = 90 minutes

His initial speed was 68mph. Using Distance = Rate * Time, we get: Let r = speed for 6 hours, r-20 = speed for 5 hours, so: 648 = 6r + 5*(r - 20). Hope this wasn't in Wi because the max legal speed limit is 65mph!
