в пользе которых
можно быть твёрдо уверенным –
это языки и математика»

Интегрированный урок алгебры и английского языка

Check-in at the hotel

Task 1.
There are only 16 vacant rooms in the hotel. They are double rooms and triple rooms. How many double and triple rooms does the group of 36 students need?

Tour to the Tower of London

Task 2.

Group tickets are 5 pound cheaper than individual tickets. But we’ve bought only 14 group tickets for the group of 16, because two students had bought two tickets separately without any discount. We paid 250 pounds for all 16 tickets. The question is “how much money did these two individual students pay for their 2 tickets?”

Tower bridge

Task 3.
A group of tourists is heading to the hotel. And the other group is going on an excursion to the Tower. If the first group leaves 1 hour earlier than the second one, then the meeting will take place in the middle of the way. If they leave at the same time, they will meet in 45 minutes. Find the speed of tourists and the distance between the Tower and the hotel, if it is known that the speed of one group is 4 km per hour more than the speed of the other.
