Nolan just drove at a constant rate for 5 hours here is now 340 miles from where he started. A. At what rate was he driving? B. Nolan has another 204 miles to go. If he continues to drive at the same rate, how long will it take him?

Sagot :

A) 68 mph. B) 3h

1) Gathering the data

time: 5 hours

Space= 340 miles

A) To find the rate, we can calculate it by simply writing a quotient between the Space and the time, (since Nolan is constantly moving

[tex]V=\frac{340}{5}=68\text{ mph}[/tex]

So Nolan was at 68 mph

B) We can find out by setting a proportion since it's been said that the speed is constant. 340 miles have already been driven there are 204 miles to go.

340------5 hours

204 ---- x

340x = 204 *5 Divide both sides by 340

x=3

So it will take more 3 hours so that Nolan can finish his trip.
