So, we need to do the distance she travelled (21 miles) divided by the rate at which she travelled (4 hours). Therefore, because 21 divided by 4 is 5.25, she biked at a speed of 5.25 mph (Miles per hour). So, if she bikes 5.25 miles every hour we can divide 42 by 5.25 to get the time it would take her to travel 42 miles. Now, 42 divided by 5.25 equals 8, so that means for Shelly to bike 42 miles at her average speed of 5.25 mph, it would take her 8 hours.

The distribution of the -4 was incorrectly put in as -4b when it should be 4b
Answer:
g = 3/7
Step-by-step explanation:
7/(3/2)
= 7 x (2/3)
= ( 2 x 7 )/3
= 14/3
14/3 = 2/g
Cross multiply,
14 x g = 3 x 2
g = ( 3 x 2 )/14
14 can be written as 2 x 7.
g = ( 3 x 2 )/( 2 x 7 )
2 in both numerator and denominator gets cancelled.
g = 3/7
