The Ostrich will take 64 minutes to cover 40 miles.
Data;
To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).
[tex]25mi = 40 min\\40 mi = x min[/tex]
Cross multiply both sides
[tex]x * 25 =40 * 40[/tex]
simplify the value
[tex]x*25=40*40\\25x = 1600\\[/tex]
divide both sides by the coefficient of x
[tex]25x = 1600\\25x/25 = 1600/25\\x = 64[/tex]
From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.
