Question

An ostrich can run 25 miles in 40 minutes. How many minutes will it take the ostrich

Answer 1

Step-by-step explanation:

25 miles / 40 minutes is the reference speed.

speed is always expressed in distance/time.

for different distances the ratio of rate between distance and time must be the same, if the speed is truly the same.

so,

25 miles / 40 minutes = 40 miles / x minutes

x minutes × 25 miles = 40 minutes × 40 miles

x minutes = 40 minutes × 40 miles / 25 miles =

= 40 minutes × 8/5 = 8×8 = 64 minutes

the ostrich will need 64 minutes for 40 miles.

Answer 2

It will take the Ostrich 64 minutes to run 40 miles, at the same speed

The distance-time ratio is given as:

Distance : Time = 25 miles : 40 minutes

When the distance is 40 miles, the ratio equation becomes

40 miles : Time = 25 miles : 40 minutes

Express as fraction

$\frac{Time}{40} = \frac{40}{25}$

Multiply both sides by 40

$Times = \frac{40}{25} * 40$

Solve for times

$Time =64$

Hence, it will take 64 minutes to run 40 miles
