Convert miles per hour to meters per second. round the answer to the nearest whole number. (1 mile = 1,609 meters, 1 hour = 3,600 seconds)

Miles per hr to meters per second...

1609(meters) / 3600(seconds) = 0.45 meters per secondround to the nearest whole number = 0 <== I am not sure about this...if u didn't have to round, it would be 0.45 meters per second...but rounding...it is closer to 0 then 1...and 0 is a whole number

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
