Question 5

Step1: Identify what to solve for

We are solving for Time. The formula relating speed (\(v\)), distance (\(d\)) and time (\(t\)) is \(t=\frac{d}{v}\).

Step2: Substitute values

Given \(v = 110\) miles/hour and \(d=35.4\) miles. Substitute into the formula: \(t=\frac{35.4}{110}\).

Step3: Calculate the value

\(t=\frac{35.4}{110}\approx0.322\) hours.

Step1: Identify what to solve for

We are solving for Time. The formula is \(t=\frac{d}{v}\).

Step2: Substitute values

Given \(v = 1.9\) cm/s and \(d = 20\) cm. Substitute into the formula: \(t=\frac{20}{1.9}\).

Step3: Calculate the value

\(t=\frac{20}{1.9}\approx10.53\) seconds.

Step1: Identify what to solve for

We are solving for Speed. The formula relating speed (\(v\)), distance (\(d\)) and time (\(t\)) is \(v=\frac{d}{t}\).

Step2: Substitute values

Given \(d = 15\) km and \(t = 10.7\) minutes. First, we can keep the time in minutes or convert to hours. Let's keep it in minutes for now. Substitute into the formula: \(v=\frac{15}{10.7}\).

Step3: Calculate the value

\(v=\frac{15}{10.7}\approx1.402\) km/minute. If we want in km/hour, since 1 hour = 60 minutes, \(v=1.402\times60 = 84.12\) km/hour (approx). But using the given time unit (minutes), the speed is \(\approx1.402\) km/minute.
