Question

Nick skates 2 1/8 miles in 1/2 of an hour. What is Nick's average speed, in miles per hour ?

Answer 1

Average speed = distance / time

From the question;

distance = 2 1/8 miles = 17/8 miles

time = 1/2

substitute the values into the formula;

`\text{Average sp}eed\text{ =}((17)/(8))/((1)/(2))`
`=(17)/(8)*(2)/(1)`
`=(17)/(4)`
`=4(1)/(4)\text{ miles per hour}`
