Answer asap! double check! how do instantaneous speed and average speed differ? instantaneous speed happens all the time, but average speed only happens once per hour. instantaneous speed is always faster than average speed. instantaneous speed is the speed of an object at a specific time, but average speed is the total distance over the total time. instantaneous speed is always slower than average speed.

Aperson takes a trip, driving with a constant speed of 89.5km/h, except for a 22.0−min rest stop. if the person's average speed is 77.8km/h , how much time is spent on the trip and how far does the person travel? average speed: let a body covered d1,d2,d3 distances in respective time intervals t1,t2 and t3. . then the average speed of the body is given by average speed=total distancetotal time=d1+d2+d3t1+t2+t3.
