The distance between Lagos and Ibadun is 120km. A driver took 45mins to cover the distance. What was his average speed km/h
Show workings bit by bit
To find the average speed of the driver, we need to use the formula:
Average speed = distance ÷ time
We are given that the distance between Lagos and Ibadan is 120km, and the driver took 45 minutes to cover the distance. However, the formula requires time to be in hours, so we need to convert 45 minutes to hours by dividing by 60:
45 minutes ÷ 60 = 0.75 hours
Now we can substitute the values into the formula:
Average speed = 120 km ÷ 0.75 hours
Simplifying the expression:
Average speed = 160 km/h
Therefore, the driver's average speed was 160 km/h.
To find the average speed in km/h, we need to divide the total distance traveled by the time taken.
Step 1: Convert the time taken to hours:
45 minutes is equal to (45/60) hours, as there are 60 minutes in an hour.
Hence, 45 minutes is equal to 0.75 hours.
Step 2: Divide the distance by the time to find the average speed:
Average Speed = Total Distance / Time Taken
Average Speed = 120 km / 0.75 hours
Step 3: Calculate the average speed:
Average Speed = (120 km / 0.75 hours)
Average Speed = 160 km/h
Therefore, the average speed of the driver is 160 km/h.
To find the average speed, we will use the formula:
Average Speed = Total Distance / Total Time
1. Convert the time from minutes to hours:
45 minutes = 45/60 = 0.75 hours
2. Calculate the average speed:
Average Speed = 120 km / 0.75 hours
Divide 120 by 0.75:
Average Speed = 160 km/h
Therefore, the driver's average speed was 160 km/h.
