Oliver runs for 7 more minutes than Bobby. The equation v = 7 + b, where v represents the number of minutes Oliver runs, and b represents the number of minutes Bobby runs, shows this relationship. If Oliver runs 34 minutes, how many minutes does Bobby run?

27 minutes.

Step-by-step explanation:

We have been given that Oliver runs for 7 more minutes than Bobby. The equation , where v represents the number of minutes Oliver runs, and b represents the number of minutes Bobby runs, shows this relationship. We are asked to find number of minutes for which Bobby run, if Oliver runs 34 minutes.

To solve our given problem, we will substitute in our given equation as:

Upon subtracting 7 from both sides, we will get:

Therefore, Bobby ran for 27 minutes.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
