Sarah 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 Sarah travel each minute?
Assuming Sarah travelled in a constant speed
she travelled 15 miles in 2 hours, so 15/2= 7.5 so she goes 7.5 miles per hour
each miles is 1760 yards, 1760*7.5= 13200 yard
so we know that she travelled 13200 yards in an hour, there are 60 mins in an hour
applying the equation distance/time = speed
we get 13200/60 = 220
so she travels 220 yards every mins
