Mathematics textbook for 5th grade:
Travelling past the GIBDD station at a speed of 105 km / h, the owner of the Oka car did not stop at the signal of an inspector. Two minutes later, the indignant inspector rushed after him on a BMW motorcycle, but, having developed a speed of about 210 km / h, did not notice how he overtook the offender. Ten minutes later, he realized his mistake and turned and, reducing the speed to 15 km / h, went to meet him. After what time after the turn the inspector meets Oka?"
I have two questions about this task:
What did the authors of the textbook smoke?
How much money does an OKI driver give to the DPS inspector?
