An ostrich can run 25 miles in 40 minutes. How many minutes will it take the ostrich to run 40 miles if it runs at the same spee
fenix001 [56]

The Ostrich will take 64 minutes to cover 40 miles.

Data;

  • rate = 25 miles in 40 minute

<h3>Rate</h3>

To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).

25mi = 40 min\\40 mi = x min

Cross multiply both sides

x * 25 =40 * 40

simplify the value

x*25=40*40\\25x = 1600\\

divide both sides by the coefficient of x

25x = 1600\\25x/25 = 1600/25\\x = 64

From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.
