A bus travels 90 km in 1.5 hours (with a constant speed). How far can it travel in 7.2 hours (with the same speed)?​
blondinia [14]

Answer:

distance=90km

time=1.5h

speed of the bus=distance /time

speed of the bus=90km/1.5h

speed of the bus=60km/h

therefore if 1.5h=60km/h

then 7.2h=(7.2x60)/1.5 =288km

Nate's savings account for the business had $12.10 more at the end of the year than the $252 it had at the begining of the year.
Ulleksa [173]
4.58% is the answer. You need to add the $12.10 to $252 to get the total. 252x100%=2500÷264.10 then subtract the answer from 100.
