Question

An automobile traveling along a straight road
increases its speed from 24 ft/s to 37 ft/s in
180 ft.
If the acceleration is constant, how much
time elapses while the auto moves the 180 ft?
Answer in units of s

Answer 1

The average speed while traveling the 180 ft is given by:
\[\large Average\ speed\ while\ accelerating=\frac{24+37}{2}\ ft/s\]
The elapsed time while the auto moves the 180 ft is given by the distance divided by the average speed:
\[\large Elapsed\ time=\frac{180\times2}{(24+37)}=(you\ can\ calculate)\ s\]
