A. What was her speed in miles per hour?

Write an equation to show the relationship between t (time) and
d (distance traveled)

c. If she continues to drive at the same speed, how many miles can she go in 75 hours

d. After 7.5 hours, she decides to decrease her speed to 3/4 of her earlier speed. What is her
new speed?

Answer 1

Answer:

a - 56mi/h

b - confuzzled so heres the rearranged formulas?

speed = distance/time

time = distance/speed

distance = speed x time

c - 4200 miles

d - 42mi/h

Step-by-step explanation:

s=d/t

196/3.5=56

56x75=4200

1/4 of 56

56/4= 14

14x3=42
