7 0

Answer: 3

Explanation:

She wants to get 70%, so we need to solve

x/20 = 70/100

Doing so gets us

100x = 20*70

100x = 1400

x = 1400/100

x = 14

She needs to have 14 questions correct, out of 20, to get a score of 70%

14/20 = 0.70 = 70%

She needs to get 14-11 = 3 more correct questions.

kkurt [141]

Step-by-step explanation:

Convert the speeds of Amir and Ryder to meters per second (m/s).

Amir:

8260 mm/s = 8.260 m/s

Ryder:

930 cm/s = 9.30 m/s

9.30 m/s > 8.260 m/s, so:

Ryder ran approximately 1 meter per second faster than Amir.
