rate = distance / time; so (390 mi)/(13 hr) = 30 mi/hr, also known as 30 mph
The most important formula to memorize is: Distance = Rate (speed) x Time (hours or minutes, etc..) Therefore, the average rate on the first date can be calculated as follows: Rate = Distance / Speed 348 miles divided by 6 hours = 58 miles per hour. At that rate, a total of 58 miles times 9 hour = 522 miles can be driven by the family in the next 9 hours.
To get the rate for 250 miles in 5 hours, divide the miles by the hours to get miles per hour, 250 miles/5 hours=50 miles per hour. If you divide 5 hours by 250 miles, you get 0.02 hours per mile, the other unit rate for this set of numbers.
To determine the unit rate of the go-kart driver, divide the total distance driven by the total time taken. In this case, you would calculate 53 miles divided by 16 hours, which equals approximately 3.31 miles per hour. This means the unit rate is about 3.31 miles per hour.
His rate is 4 miles per hour.
360 ÷ 6 = 60 miles per hour is the unit rate
To find the unit rate of 180 miles in 3 hours, divide the total distance by the total time. So, 180 miles ÷ 3 hours = 60 miles per hour. Therefore, the unit rate is 60 miles per hour.
at the rate of 30 miles per hour it would take 1 hour. at the rate of 30 miles per hour it would take 1 hour.
Distance = Rate * Time or, for our purposes Time = Distance/Rate Time = 323 miles/70 miles per hour = 4.61 hours -----------------
The rate of speed is 11.43 miles per hour
Matts speed was 320/5 miles per hour. At 320/5 mph he could have driven 9*320/5 miles = 9*64 = 576 miles.
20 miles per hour.
Distance = rate * time. (55 miles/hour) * (4 hours) = 220 miles
