Question

A plane flies 1440 miles at a speed of 240 mph how long does it take?

Answer 1

speed times time=distance
st=d
we want ot find time so isolate t
st=d
divide both sides by s
t=d/s

distance=1440
speed=240
t=1440/240=6
the times was 6 hours since mph his miles per HOUR

6 housr

Answer 2

Speed =
`(distance)/(time)`

240 =
`(1440)/(time)`

Rearrange;

time =
`(1440)/(240)`

time = 6 hours
