Question

If an automobile travels 450 yards in 15 seconds, how many feet does it travel in 1/3 of a second?

how do I calculate this problem?

Answer 1

You can calculate it from the formula for velocity
v=
`(s)/(t)`
if it travels 450 yards in 15 seconds
s=450 yards t= 15s
1 yard = 3 feet so
s= 1350 feet
v=
`(1350)/(15)=90 (feet)/(s)`
so if in one second it travels 90 feet, in
`(1)/(3)` of a second it travels
`(90)/(3) =30` feet
