10.8 seconds

Explanation:

Use the formula distance equals the product of rate and time.

d=rt

Note that you need to make sure the distance unit (km or m) is the same, and change hours to seconds.

25 kilometres = 25,000 meters
1 hour = 3600 seconds

Rearrange the equation to solve for time:

d/r=t

t=(75m)/(((25000m)/(3600s)))

Multiply 75m by the reciprocal of the rate (dividing fractions)

t=75m*((3600s)/(25000m))

t=(75m*3600s)/(25000m)

t=(75cancelm*3600s)/(25000cancelm)

t=(270000s)/25000

t=10.8s
