(780-60x3):(90+60)=4

Answer 2

Calculating the Time of the Car Meeting

To calculate the time it took for the car to meet, we can use the formula: time = distance / speed.

Given: - Distance between the two cities = 780 km - Speed of the truck = 60 km/h - Speed of the car = 90 km/h - Time taken by the car to meet the truck = ?

Using the formula, we can calculate the time taken by the car to meet the truck.

The time taken by the car to meet the truck is calculated as follows: time = distance / speed.

For the car: time = 780 km / 90 km/h = 8.67 hours.

So, the car was in transit for approximately 8.67 hours before meeting the truck.
