V = ( 90 km/hr)( 1000 m/km ) ( 3.2808 ft/m )( 1 mi/5280 ft ) = 55.9 mph <------
___________________________________________
1 mile = 1.609 km
90 km/hour = 90/1.609 miles/hour = 55.935 miles/hour
90 miles per hour is 144.84 kilometers per hour.
90 miles/hour (5280 feet/1 mile)(1 hour/3600 seconds) = 132 feet per second ================
The average speed is calculated by dividing the total distance by the total time. In this case, the average speed would be 16 km/hour since 24 km divided by 1.5 hours (90 minutes converted to hours) equals 16 km/hour.
The speed of a 90 mph pitch as it crosses the plate would likely be a little less than 90 mph, as there is air resistance and friction that can slow the pitch down slightly.
It depends on how long the object is. If the object is a dot, it will take 1.5 sec. This is not true, the size of the object is not important. If it is a car, a fly, or a plane it is all the same! If you take 90 mi/hr and multiple it by 5820ft you get ft/hour. This is 523800 ft/hr. Then divide this by 60 to get ft/min which is 8370, then divide it by 60 to get ft/sec., which is 145 ft/sec. Since you are only going 60 ft. divide 60/145 this is .41 sec. So it takes about a 1/2 sec. at 90 miles an hour to go 60ft.
90 kilometers per hour is 55.92 miles per hour.
90 miles per hour.
90 metres/ sec = 324 km / hour = 201.3 miles/hour
About 90 Kilometers.
Rounded to two decimal places, 90 metres per second is approximately equal to 201.32 miles per hour.
It would be 90 miles per hour
90 kph = 55.9 mph
Speeding.
90 mph = 144.8 kph (rounded)
90 miles = 145 kilometres, approx so 90 mph = 145 kilometres per hour.
90 miles per hour is 144.84 kilometers per hour.
It would only take you about 3 minutes and 18 seconds to drive five miles at 90 miles per hour.
