Answer:
Given: distance = 90 km = 90000 m, time = 1 hour 15 minutes = 4500 s
Concept Used: In this type of question, average speed of the car can be calculated by using below formula
Formula Used: Average Speed = (Total Distance / Total Time)
Calculation: using the above formulae, we get
⇒ Average Speed = (90000 / 4500) m / s = 20 m / s
∴ Average Speed = 20 m / s.
