Ashley can ride her bicycle 15 miles in 2 hours. there are 60 minutes in 1 hour, and there are 1,760 yards in 1 mile. how many yards does ashley travel?

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
