Question

Sarah flies from Oklahoma City to Dallas-Ft. Worth in 30 minutes. The air distance is 175 miles. what formulas can calculate the speed of the plane?

Answer 1

speed= distance divided by time

speed=`175/(1/2)=175xx2=350` miles per hour

Answer 2

`color(red)("Speed"="Distance"/"Time"`

Explanation:

Time taken to complete the journey `=30` mins

Distance`=175` miles

To calculate the speed, we use the formula:

`color(red)("Speed"="Distance"/"Time"`

In this case, `"Speed"=175/30"miles/min"`

`color(magenta)(=>5.83" miles/min"` [Rounded]

`therefore` The speed of the plane is `color(magenta)(5.83 " miles/min"`

Converting the answer into the SI unit; i.e. `color(darkorange)("m/s"`

`=>5.83xx1609.34/60`

`color(purple)(=>156.37 "m/s"`

~Hope this helps! :)
