Just divide the number of miles by the number of hours.In this example, you get the same result in both cases, meaning that - as far as we can tell - the speed may be constant.
It is 65 miles per hour
To convert the time from minutes to hours, divide by 60, since there are 60 minutes in an hour. 42 minutes ÷ 60 = 0.7 hours To find the speed in miles per hour, divide the distance by the time. 3 miles ÷ 0.7 hours = 4.29 miles per hour Therefore, 3 miles in 42 minutes is approximately 4.29 miles per hour.
804 miles in 16 hours = 804/16 = 50.25 miles per hour.
30 miles per hour.
Oh, dude, that's like a piece of cake. So, if you're going 120 miles in 3 hours, you just divide 120 by 3, which gives you 40 miles per hour. So, like, you're cruising along at 40 miles per hour. Easy peasy lemon squeezy.
The change in distance divided by the change in time. (21-7 miles)/(3-1 hours)=14/2=7 miles/hour or 7 mph.
There is no way to answer the question as asked, because time (hours) and distance (miles) are not the same. If the question was phrased: How many hours were spent driving at 207 miles and the miles per hour were 55 mph, then the answer would be 3 hours and 45 minutes. Rephrase the question, give the miles per hour, and then the question can be answered.
this is a statement not a question
This seems to be a trick question, but the answer is 18 hours, as given in the question itself.
zero
At 1 mile per hour it is 55 hours, at 2 miles an hour it is 27.5 hours at 5 miles an hour it is 11 hours at 55 miles an hour it is 1 hour at 60 miles an hour it is 55/60 hour or 55 minutes at 120 miles an hour it is 27.5 minutes at 550 miles an hour it is 6 minutes etc
The rate of change is 140 miles / 4 hours or 35 miles / 1 hour or 35 miles per hour.. It can also be expressed as 4 hour / 140 miles or 1 hour / 35 miles or 1/35 hour per mile traveled. Therefore, If you know either the distance traveled or thye elapsed time, you can figure out the other value.
At 60 miles per hour, six hours. At 30 miles per hour, twelve hours.
84 miles18 miles/hour * 3 hours = 54 miles15 miles/hour * 2 hours = 30 miles54 miles + 30 miles = 84 miles
1 hour at 14 miles per hour. 2 hours at 7 miles per hour.
45 miles in three hours at 15 miles per hour.
Did you read your question before posting it? Apart from the fact that few cars can travel at 350 miles per hour, the question asks how much time ...[for] ... 3 hours. The answer, obviously, is 3 hours!
