An ostrich can run at speeds of up to 72 km/h. How long will it take an ostrich to run 1.5 km at this top speed?
1.5 km/72 km/h = 0 0208 h
= 1.25 minutes = 75 seconds

An ostrich can run at speeds of up to 72 km/h. How long will it take (in seconds) an ostrich to run 1.5 km at this top speed?
75 seconds.
To find the time it takes for an ostrich to run 1.5 km at a speed of 72 km/h, we can use the formula:
Time = Distance / Speed
Plugging in the values, we have:
Time = 1.5 km / 72 km/h
To simplify the calculation, we can convert the speed from km/h to m/s, as the unit of distance is in kilometers.
1 km = 1000 m
1 hour = 3600 seconds
So, the speed of an ostrich in m/s can be calculated as follows:
72 km/h * (1000 m/km) / (3600 s/h) = (72 * 1000) / 3600 m/s
Simplifying further:
Speed = 20 m/s
Now, we can substitute the values into the formula:
Time = 1.5 km / 20 m/s
Simplifying further:
Time = 0.075 hours
To convert hours to minutes, multiply by 60:
Time = 0.075 hours * 60 minutes/hour
Simplifying further:
Time = 4.5 minutes
Therefore, it will take an ostrich approximately 4.5 minutes to run 1.5 km at its top speed of 72 km/h.
