Question

A race car driver won a 900 mile race with a speed of 178.9 miles per hour. find the​ driver's time.

Answer 1

We need to find driver'side time. We will start by using formula for speed and solve for time.
Speed(S)=distance (d)/time (t) and S=178.9mph d=900 miles
S=d/t
(t)S=(d/t)(t)
tS=d
tS/S=d/S
t=d/St
t=900miles/178.9mph
t=5.03hrs
