Question

ПОМОГИТЕ ПОЖАЛУЙСТА!!!!!!!!!!!!От пристани на остров одновременно отправились катер и теплоход.Скорость катера равна 30 км в час ,а скорость теплохода на 12 км в час больше .Какое расстояние будет между ними через 2 часа?

Answer 1

Раз у теплохода скорость на 12 км в час больше,значит 12*2=24км будет расстояние между ними

Answer 2

Calculation of the Distance between the Boat and the Ship

To calculate the distance between the boat and the ship after 2 hours, we need to consider their respective speeds.

Given that the speed of the boat is 30 km/h and the speed of the ship is 12 km/h faster than the boat, we can calculate the speed of the ship as follows:

Speed of the ship = Speed of the boat + 12 km/h

Therefore, the speed of the ship is 30 km/h + 12 km/h = 42 km/h.

To calculate the distance between the boat and the ship after 2 hours, we can use the formula:

Distance = Speed × Time

For the boat, the distance traveled after 2 hours is:

Distance of the boat = Speed of the boat × Time = 30 km/h × 2 hours = 60 km

For the ship, the distance traveled after 2 hours is:

Distance of the ship = Speed of the ship × Time = 42 km/h × 2 hours = 84 km

Therefore, the distance between the boat and the ship after 2 hours is:

Distance = Distance of the ship - Distance of the boat = 84 km - 60 km = 24 km.

So, the distance between the boat and the ship after 2 hours is 24 kilometers.
