2)180:90=2(ч.)

через 2 часа

Answer 3

Calculation of Time and Distance between Two Rhinos

To calculate the time it takes for the two rhinos to be 180 km apart, we can use the formula:

Time = Distance / Relative Speed

Let's calculate the time it takes for the two rhinos to be 180 km apart.

The speed of one rhino is 40 km/h, and the speed of the other rhino is 50 km/h.

Step 1: Calculate the relative speed of the two rhinos.

The relative speed is the sum of their individual speeds.

Relative Speed = 40 km/h + 50 km/h = 90 km/h

Step 2: Calculate the time it takes for the two rhinos to be 180 km apart.

Time = Distance / Relative Speed

Time = 180 km / 90 km/h = 2 hours

Therefore, it will take 2 hours for the two rhinos to be 180 km apart.
