Question

Из города выехала грузовая машина со скоростью 60 км/ч. Одновременно с ней выехала легковая машина. Через 2 ч она обогнала грузовую на 40 км. С какой скоростью ехала легковая машина?

Answer 1

Calculation of the Speed of the Car

To determine the speed of the passenger car, we can use the information provided in the question.

Given: - The truck is traveling at a speed of 60 km/h. - After 2 hours, the passenger car overtakes the truck and is ahead by 40 km.

To find the speed of the passenger car, we can calculate the distance traveled by both vehicles in the given time.

The distance traveled by the truck in 2 hours is: 60 km/h * 2 hours = 120 km

Since the passenger car overtakes the truck and is ahead by 40 km, the distance traveled by the passenger car in 2 hours is: 120 km + 40 km = 160 km

To find the speed of the passenger car, we can divide the distance traveled by the passenger car by the time taken: 160 km / 2 hours = 80 km/h

Therefore, the passenger car was traveling at a speed of 80 km/h.
