Bob had to ride his bike 32 miles in 5 hours. what was his speed in miles per hour?

s = 6.4 or 32/5

Step-by-step explanation:

Bob rode 32 miles in 5 hours. Lets put this into an equation. Lets say the variable s is his speed in miles per hour.

5s = 32

Solve for s.

÷ 5 both sides.

s = 32/5

simplify (or not)

s = 6.4 or s = 32/5

I hope this helps. :)

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

a. is correct
