An athlete runs 8 miles in 50 minutes on a treadmill. at this rate, how long will it take the athlete to run 9 miles? *

It will take the athlete 56.25 minutes to run for 9 miles

If an athlete runs 8 miles for a specified period of time of 50 minutes.

Then, in a single mile journey, the athlete ran for a period of time:

= (1 mile × 50 minutes)/ 8 miles

= 6.25 minutes

Now, in 9 miles, the athlete will run for :

= 6.25 × 9 minutes

= 56.25 minutes

50 minutes = 50/60 hours = 0.8333333333 hours

8 miles / 0.8333333333 hours = 9.60 miles per hour

9 miles / 9.60 miles per hour =

0.9375 hours = 56.25 minutes

Step-by-step explanation:

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m
