250
A fighter jet.
To convert seconds to minutes, you divide the number of seconds by 60 since there are 60 seconds in a minute. Therefore, 750 seconds divided by 60 equals 12.5 minutes. So, there are 12 minutes and 30 seconds in 750 seconds.
45,000 seconds.
750 x 60 = 45000
Sound travels at a speed that is dependent on density. As a rule the more dense the material the faster sound travels. In air, mach 1 (the speed of sound) is about 750 MPH. In water it is about 3316 MPH. (Water is much denser than air.)
An example: A football travels at A speed unknown. Measure A distance for travel. Throw the ball and time it with A stopwatch. Take the feet and devide by seconds. 100feet, for 8seconds = 12.5 feet/per second. multiply 12.5 (feet) by 60 (seconds in A minute) =750 feet/per minute multiply 750 (feet) by 60 (minutes in an hour) = 45,000 feet/per hour. Divide 45,000 (feet) by 5,280 (feet in A mile) = 8.522 Miles/per hour This will work for any measuring scale, You just need to know all the different measurement steps. I.E. - feet in A mile, seconds in A minute, minutes in an hour. ECT.
750 minutes
750 divided by 15 = ____ mph (speed)
Top speed of a 2007 gsxr 750 is 957 MPH....
12.5 minutes x 60 seconds/minute = 750 seconds
750 - 20% = 750 x (1 - (20/100)) = 750 x 0.8 = 600 Therefore, 750 - 20 percent is equal to 600.
The result is 600 seconds or a decrease of 150 seconds.
