To calculate the time it takes to travel a distance at a given speed, we need to convert the units to ensure consistency.
First, let's convert the distance from kilometers (km) to feet (ft). 1 km is approximately equal to 3280.84 ft.
Therefore, 2 km is equal to: 2 km * 3280.84 ft/km = 6561.68 ft
Now, we can calculate the time using the formula: time = distance / speed.
Given that the speed is 45 ft/sec and the distance is 6561.68 ft, we can substitute these values into the formula:
time = 6561.68 ft / 45 ft/sec
Calculating the time:
time ≈ 145.82 seconds
Rounding to two decimal places, it will take approximately 145.82 seconds to travel 2 km at a speed of 45 ft/sec.
