In the formula d=rt d represents distance in miles, r represents average speed in miles per hour, and t represents time in hours.What is an automobiles average speed if it travels 60 in 1 1/2 hours?
d = rt
60 = 1.5r
40
Well, if an automobile travels 60 miles in 1 1/2 hours, that means it's really in a hurry to get somewhere! I guess it's because it doesn't want to be stuck in traffic. But let's get back to the question at hand. To find the average speed, we can use the formula d=rt. In this case, d is 60 miles, and t is 1 1/2 hours. So, r=60/(1 1/2). Now let's calculate that. Remember, it's always good to check your math before submitting any answers. Quick, get your calculator!
To find the average speed of an automobile, we need to use the formula:
average speed (r) = distance (d) / time (t)
In this case, the distance traveled (d) is given as 60 miles, and the time taken (t) is given as 1 1/2 hours.
Now, let's substitute these values into the formula to calculate the average speed:
r = 60 miles / 1.5 hours
To simplify this expression, we can divide 60 by 1.5:
r = 40 miles per hour
Therefore, the automobile's average speed is 40 miles per hour.
To find the average speed of an automobile, you can use the formula d = rt, where d represents the distance, r represents the average speed, and t represents the time taken. In this case, the distance traveled is given as 60 miles, and the time taken is 1 1/2 hours.
To find the average speed, we need to rearrange the formula to solve for r. Dividing both sides of the equation by t, we get:
r = d/t
Now, substitute the given values into the equation:
r = 60 miles / 1.5 hours
To simplify the calculation, we can convert 1 1/2 hours to a fraction. 1 1/2 is the same as 3/2, so the equation becomes:
r = 60 miles / (3/2) hours
To divide by a fraction, we can multiply by its reciprocal. So, we can rewrite the equation as:
r = 60 miles * (2/3) hours
Now, we can cancel out the units of miles and hours:
r = 40 miles/hour
Therefore, the average speed of the automobile is 40 miles per hour.
