Question

the equation for distance is $d = st$. if a car has a speed of $77.0$ m/s and travels for $45.0$ seconds, how far does it go?
a. $5110$ m
b. $3465$ m
c. $1.71$ m
d. $2220$ m

Explanation:

Step1: Substitute the values into the formula

Given \(s = 77.0\ m/s\) and \(t=45.0\ s\), substitute into \(d = st\).
\(d=77.0\times45.0\)

Step2: Calculate the product

\(77\times45=(70 + 7)\times45=70\times45+7\times45=3150+315 = 3465\)

Answer:

B. \(3465\ m\)
