At highway speeds, a certain car is capable of an an acceleration of about 1.7 m/s^2. At this rate, how long does it take to accelerate from 90 km/hr to 110 km/hr? (WATCH UNITS.)(adsbygoogle = window.adsbygoogle || []).push({});

Given- Time=?

A=1.7m/s^2

Vi=90km/hr

Vf=110km/hr

Vf=vi+at Solve for t! T= vf-vi/a 110km/hr-90km/hr = 20km/hr

1.7m/s^2

How do I divide 20km/hr by 1.7 m/s^2?
