The average speed of the food cart to the nearest tenth of a m/s is 0.3 meter per second.
How do we calculate speed?
Speed of any moving body will be calculated by using the below formula as:
Speed = Distance / Time
Given that, Distance travelled to the right side = 4.5m
Time to travel = 15 sec
On putting values on the above equation, we get
Speed = 4.5 / 15 = 0.3 m/s
Hence required speed is 0.3m/sec.
