Lamar has been running sprints tp prepare for his next football game. He has found that he can maintain his maximum speed for 45 yards. He's thinking of running in a 5 km race in a few months, but doesn't know if he can maintain his maximum speed for the entire 5 km. Can you help him determine how far he can?

Answer and Explanation:

Given that

Length of race = 5km

Maximum speed = 45 yards

Based on the above information,

We transform the yards to kilometer i.e.

1 km = 1093.613 yards

And,  

x = 45 yards

So,

1093.613 × x = 45

x = 45 ÷ 1093.613

x = 0.0411480 km

Where

x = Maximum length for which the maximum speed demonstrated in kilometers is sustained.

So, we concluded that Lamor cannot go for the overall 5km as he maintained till 0.0411 km
