Well, honey, it all depends on how fast you're driving. If you're cruising at a steady 60 miles per hour, it should take you about 21 minutes to cover those 21 miles. But if you're stuck in traffic or driving like a grandma, well, buckle up because it could take a lot longer. Drive safe, darling!
The time it takes to travel 21 miles by car depends on the speed at which you are driving. If you are traveling at a constant speed of 60 miles per hour, it would take approximately 21 minutes to cover the distance. However, if you are driving at a slower speed, such as 30 miles per hour, it would take approximately 42 minutes to travel 21 miles. It's important to consider traffic conditions, road quality, and other factors that may affect your travel time.
Oh, dude, it's like simple math, but I get it. So, if you're driving at, say, 60 miles per hour, you'd cover 21 miles in about 21 minutes. But, like, don't forget about traffic, road conditions, and your grandma driving in the fast lane at 40 miles per hour. So, it could take anywhere from 20 to 30 minutes, give or take.
last month when he used 21 gallons of gas
Bermuda is 21 miles in length and it's largest width is 1 mile.
You can divide the number of miles by the number of gallons, to get miles per gallon.Or you can divide the other way (the number of gallons by the number of miles), to get gallons per mile. Each of the above will be a unit rate, but in this particular case, it is more common to calculate miles per gallon.
Assuming that his acceleration was linear (ie. that he slowed down at a perfectly steady rate), then you can say his velocity at any point in those eight seconds was: 21 - t(21 / 8) m/s To get the distance covered in that time, you can simply take the area under that line between 0 seconds and eight seconds. Because it's linear, this is very easy. You're dealing with a right triangle that is 8 seconds wide and 21 meters per second tall. With a triangle, the area is equal to half it's width times it's height, so the equation is: d = 21m/s * 8s / 2 ∴d = 168m / 2 ∴d = 84m. So he traveled 84 meters in those 8 seconds, and probably scared the bejeebers out of that poor deer. Average speed = 21/2 m/s , Time =8 s, Distance = 8 x 21/2 = 84m
2x-3=10x+21 2x-3-2x=10x+21-2x -3=8x+21 -3-21=8x+21-21 -24=8x -3=x
