Agirl is pedaling her bicycle at a velocity of 2.35 km/min. how far will she travel in 2 hours?

282 km

Step-by-step explanation:

Use formula

where

d - distance

v - velocity

t - time

In your case, t = 2 hours. Note that 1 hour = 60 minutes, so 2 hours = 120 minutes.

v = 2.35 km/min

Hence,

43

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
