Determine the time it will take Warren to run the 10-kilometer race in October if he runs at the same rate as in April.
Find Warren's running rate in April.
Warren ran 5 kilometers in 30 minutes. His rate is calculated as:
Rate=TimeDistance=30min5km=61km/min.
Calculate the time required to run 10 kilometers at the same rate.
Using the rate 61km/min, the time t to run 10 kilometers is:
t=RateDistance=61km/min10km=60min.
The time it will take Warren to run the 10-kilometer race in October is 60min.
The time it will take Warren to run the 10-kilometer race in October is 60min.
