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

If Ashley can ride her bicycle 15 miles in 2 hours, then in order to find how many yards she travels in that time, we simply multiply miles/hour by yards/mile to yield yards/hour. So 15 miles in 2 hours * 1760 yards in 1 mile yields a yardage distance of 28160 yards ridden in the two-hour period.
