The average speed of an object, s, is given by the distance of travel, d, divided by the time it takes to travel that distance, t. How would you write an equation of the time it takes to travel distance d at an average speed s?Multiple choice question.t = ds𝑑𝑠t = dst = sd

A car travels from rest with a constant acceleration a for t seconds. What is the average speedof the car for its journey, if the car moves along a straight road?(A) at2/2 (B) 2at2 (c)at/2 (D) None

A car travels at a speed of 45 m/s for a time interval T and then travels at a speed of 15 m/s for another time interval 2T. Find average speed for the total journey.

A car travels at 54 km/hr for first 20 secs , 36 km/hr for next 30 secs and finally 18 km/hr for next 10 secs. Find its average speed.

An auto travels at a rate of 25 km/h for 4 minutes, then at 50 km/h for 8 minutes, and finally at 20 km/h for 2 minutes. Find the average speed for the complete trip in meters per second. (Give the answer to one decimal place accuracy.)

A car travelled from A to B and then continued to C.It travelled from A to B at an average speed of 30 km/h.The distance from A to B is 90 km.(a) How many hours did the journey from A to B take?(b) The distance from B to C is 50 km and took 1 hour.Calculate the average speed of the whole journey from A to C
