You could use the proportion 3:1.
Per 3 feet, there is 1 yard.
For every 3 feet, there is an additional yard.
The ratio is 3 to 1, or 3:1
1/9 * 54/1 = 54/9.
So she is walking 6mph.
Answer:
speed is given by:
speed=distance/time
given that:
1 mile=1,760 yards
1 hour=60 min
then the speed in yards/sec will be:
distance Ashley covered is 15 miles
time=2 hours
thus;
speed=(15x1760)/(2x60)
=220 yards/ min
