Grete Waitz won the New York marathon nine times. The rate at which she ran during her last victory in 1988 was 26 miles in 148 minutes. To the nearest hundredth, what was the unit rate for her last race?
26/148 = x/1
148x = 26
x = 26/148
x = 0.18 mile in 1 minute
26mi/148min=13mi/74min=0.18/min
26/148 = x/1
148x = 26
x = 26/148
x = 0.18 mile in 1 minute
To find the unit rate, we need to determine the ratio of the distance to the time it took.
The distance Grete Waitz ran during her last victory in 1988 was 26 miles, and it took her 148 minutes.
To find the unit rate, we divide the distance by the time:
Unit rate = distance / time
Unit rate = 26 miles / 148 minutes
To simplify the fraction, we can divide both the numerator and denominator by their greatest common divisor. In this case, there is no common divisor other than 1.
Unit rate = 26 / 148
Calculating this division, we get approximately:
Unit rate ≈ 0.17568
So, to the nearest hundredth, the unit rate for Grete Waitz's last race was approximately 0.18 miles per minute.
