Question

What is 675,480 rounded to 4 sig figs?

In a 15 mile race, a runner finished with a time of 2 hours, 1 minute and 17 seconds. What was the runners speed in miles per hour and what was the runners pace in minutes per mile?

Answer 1

The first one is 6.754x10^5.

Answer 2

Yea i got that thanks

Answer 3

^that's not right, you have to round up because the last digit you're omitting is an 8.

675,480 -> \(6.755*10^{5}\)

Answer 4

For the second part, \(\sf speed=\dfrac{distance}{time}\)

but first you gotta convert 2 hours, 1 minute and 17 seconds to hours only

can you try that?

Answer 5

I know i already did it

Answer 6

so you got the answers?
