A reindeer runs 2014 miles in 3 hours. At that rate, how many miles does it run in 1 hour?

about 671 miles

Step-by-step explanation:

2014m=3h

2014/3= about 671 miles an hour

671.33 repeating

Step-by-step explanation:

2014/3=671.33

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

so, converting firstly the mixed fractions to improper fractions and then "adding".
