Answer:
3 [tex]\frac{31}{35}[/tex] mph ≈ 3.8857 mph
Step-by-step explanation:
Speed = distance/time
1) Plug the numbers in.
Speed = 3 ⅖ / ⅞
2) Convert the numbers to decimals.
Speed = 3.4 / 0.875
3) Solve.
Speed ≈ 3.8857 mph = [tex]\frac{136}{35}[/tex] mph = 3 [tex]\frac{31}{35}[/tex] mph
ANOTHER WAY TO SOLVE
Speed = distance/time
1) Plug the numbers in.
Speed = 3 ⅖ / ⅞
2) Convert into improper fractions
Speed = [tex]\frac{17}{5}[/tex] / [tex]\frac{7}{8}[/tex]
3) Multiply by the reciprocal
Speed = [tex]\frac{17}{5}[/tex] × [tex]\frac{8}{7}[/tex] = [tex]\frac{136}{35}[/tex] mph = 3 [tex]\frac{31}{35}[/tex] mph
