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.
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
[tex]\frac{Time}{40} = \frac{40}{25}[/tex]
Multiply both sides by 40
[tex]Times = \frac{40}{25} * 40[/tex]
Solve for times
[tex]Time =64[/tex]
Hence, it will take 64 minutes to run 40 miles
