The equation for distance is d = st. if a car has a speed of 20 m/s how long will it take to go 155m

It will take 7.75 seconds for the car to go 155m

Explanation:

From the question, we can understand that the distance covered by the moving car is got by a product of its speed and the time it travels.

i. e distance = speed X time.

However, in this case, we have the distance travelled and the speed of the car, and we are looking for the time of travel

TO solve this, we will simply make the travel time the subject of the formula in the equation above.

i. e time = distance / speed

time = 155/20 = 7.75 seconds.

Hence, it will take 7.75 seconds for the car to go 155m
