Zalmon walked 3/4 of a mile in 3/10 of an hour. What is his speed in miles per hour
He is walking 9/40 miles per hour. But in decimal form it would be 0.225
3/4 miles in 3/10 hours .... multiply both sides by 10((3/4)10 miles =(3/10) 10 hourswe get, 7.5 miles in 3 hoursdivide both sides by 3, we get 2.5 miles in an hour.so the speed is 2.5 miles per hour
