A car travels in a straight line at 67 km/h for 1 h and at 106 km/h for 2 h.
How far does it travel?
what is 67*1+106*2?

To find the distance traveled, we can use the formula:
Distance = Speed × Time
First, let's calculate the distance traveled during the first hour, when the car is traveling at 67 km/h.
Distance1 = Speed1 × Time1
Distance1 = 67 km/h × 1 h
Distance1 = 67 km
Next, let's calculate the distance traveled during the next two hours, when the car is traveling at 106 km/h.
Distance2 = Speed2 × Time2
Distance2 = 106 km/h × 2 h
Distance2 = 212 km
Finally, to find the total distance traveled, we add the distances from the two time periods:
Total Distance = Distance1 + Distance2
Total Distance = 67 km + 212 km
Total Distance = 279 km
Therefore, the car travels a total distance of 279 km.
