a boat is traveling a distance of 90 km at a speed of 30 km/s, how long will it take to reach its destination?
a 5hr
b 4hr
c 3hr
d 2.5hr

Explanation:

Step1: Recall the formula for time

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

Step2: Substitute the given values

We are given that \(d = 90\space km\) and \(v=30\space km/h\) (assuming the speed unit is \(km/h\) as \(km/s\) would be extremely fast for a boat, likely a typo). Substituting these values into the formula: \(t=\frac{90}{30}\)

Step3: Calculate the time

\(\frac{90}{30}=3\)

Answer:

c. 3hr
