Ответ:

80 км/ч

Пошаговое объяснение:

Сначала найдем расстояние

4*70=280км

S=V*t

Время у нас 3,5 часа, подставляем все данные

280=V*3,5

V=280:3,5

V=80 км/ч

By the age of 23 Beatrice
(A10) ... a number of jobs, which she (All) ... when she got tired of them.

One day she saw an
advertisement for a job as a canal warden. She applied for the job, just
because it sounded interesting, but she had no idea what a canal warden did.
Surprisingly, she (A12) ... the job and started work a few days later. Now she
(A13) ... an official cap and coat and walked along the banks of the canal,
enjoying the fresh air. It seemed to be the best job she (A14) ....

It was too good to last long.
One day as she (A15) ... along the bank, she (A16) ... into the canal. Hardly
(A17) ... shouting for help when a fellow warden (A18)... her. Later she said
she (A19) ... if she could swim. "I might still have been a canal warden
if it hadn't been for falling in the canal that day," she said.
