If a dodge viper on a test track goes a certain distance in one-half minute at 160 mph, what speed is needed to go the same distance in three-fourths minute?
:
Find the distance traveled in 30 sec (in ft)
* 30 = 7040 ft
:
Let s = speed required to go 7040 ft in 45 sec
45s = 7040
s = 7040/45
s = 156.44 ft/sec
:
In mph: = 106 mph

Actually we did not have to got thru all this, use an inverse ratio relationship
=
Cross multiply and see what you get.
