Question

Calculate the average speed of a car that travelled 720 kilometers in 6 hours

A car travels a distance of 220km in 2 hours on a tarred road. How many
kilometers can it travel in 3 hours at the same average speed?

Answer 1

The average speed of the car is 120 km/h. The car can travel 360 kilometers in 3 hours at the same average speed.

Step-by-step explanation:

To calculate average speed, you need to divide the distance traveled by the time taken. In this case, the car traveled 720 kilometers in 6 hours. So, the average speed is 720 km / 6 h = 120 km/h.

To find out how many kilometers the car can travel in 3 hours at the same average speed, you can use the formula Average Speed = Distance / Time. Plug in the values: Average Speed = 120 km/h and Time = 3 hours. Rearranging the formula, we have Distance = Average Speed x Time. So, Distance = 120 km/h x 3 h = 360 kilometers.

Answer 2

345km

Step-by-step explanation:

Find the average speed of the car.

720km ÷ 6hrs = 120km/h

220km ÷ 2hrs = 110km/h

Find the average of the 2 speeds.

`((120+110))/(2) = (230)/(2) = 115km/h`

Multiply the average by the # of hours.

115km/h × 3hrs = 345km
