Richard walks every day for exercise at a rate of 1 kilometer every 20 minutes. At this rate, how many meters can Richard walk i
n 1 hour? Complete the explanation about how you found your answer. Richard can walk meters. Since there are minutes in 1 hour, you would divide 60 ÷ 20 = . Then you would multiply 1 × 3 = to find out how many kilometers Richard walks in 1 hour. Since there are meters in 1 kilometer, you would multiply 3 × 1,000 = to convert to meters. Suppose Richard walks 1 kilometer every 15 minutes. How many meters further can he walk in 1 hour at this new rate? Complete the explanation about how you found your answer. Richard can walk meters further with this new rate. Since there are minutes in 1 hour, you would divide 60 ÷ 15 = . Then you would multiply 1 × 4 = to find out how many kilometers Richard walks in 1 hour. Since there are meters in 1 kilometer, you would multiply 4 x 1,000 = to convert to meters. So, Richard walks meters in 1 hour at his new rate. Then you subtract 4,000 − 3,000 = .
The first thing you do is cross multiply which is 3/4x=48 (3/4 = 0.75). Therfore you divide each side by .75. The left side cancels out. For the right side you divide 48 by .75 and gives you 64. x=64
