What time will a runner take to run a distance of 8 km at a speed of 15 km/hr?
s = speed
d = distance
t = time
s = d / t
t = d / s
t = 15 / 8 h
t = 1.875 h
t = 1 h 52 min 30 sec
Sorry.
My mistake.
t = d / s
t = 8 / 15
t = 0.5333...h
t = 32 min
To determine the time it will take a runner to run a distance of 8 km at a speed of 15 km/hr, you can use the formula:
Time = Distance / Speed
In this case, the distance is 8 km and the speed is 15 km/hr.
Now plug these values into the formula:
Time = 8 km / 15 km/hr
To find the answer, divide 8 km by 15 km/hr:
Time = 0.53 hours
However, it is common to express time in minutes, so multiply 0.53 hours by 60 to convert it into minutes:
Time = 32 minutes
Therefore, the runner will take approximately 32 minutes to run a distance of 8 km at a speed of 15 km/hr.
