Answer 2

Calculation of Distance Between the Bus and the Truck

To calculate the distance between the bus and the truck after 4 hours, we need to determine the distance each vehicle has traveled during that time.

Given: - Speed of the bus: 90 km/h - Speed of the truck: 60 km/h - Time: 4 hours

To find the distance traveled by each vehicle, we can use the formula:

Distance = Speed × Time

For the bus: Distance traveled by the bus = 90 km/h × 4 hours = 360 km

For the truck: Distance traveled by the truck = 60 km/h × 4 hours = 240 km

Now, let's calculate the distance between the bus and the truck after 4 hours.

To find the distance between them, we subtract the distance traveled by the truck from the distance traveled by the bus:

Distance between the bus and the truck = Distance traveled by the bus - Distance traveled by the truck

Distance between the bus and the truck = 360 km - 240 km = 120 km

Therefore, after 4 hours, the distance between the bus and the truck will be 120 km.
