The formula distance =rate x time (d = ) tells how far an object travels at a certain rate (speed) over a certain time How long will it take a train to travel 765 miles at 85 tniles per hour?

42.05 HRS

Step-by-step explanation:

D = R x T D=765 MILES R= 95 MILES/HR WE HAVE TO SOLVE FOR T BECAUSE THE QUESTIONS ASKS "HOW LONG.." T = D/R AND THEN SUBSTITUTE THE DISTANCE AND RATE ;)

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
