Question

how many speed formula for exampal​

Answer 1

Answer:

Speed

To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

Explanation:

Average speed

Time = Distance / speed = 1800/40 = 45 hours. Thus we can find the average speed as: Average Speed = (Total distance)/(Total Time) = (1800 + 1800)/(30 + 45) = 3600/75 = 48 km/hr.
