At noon mr. white started driving from boston to philadelphia at average speed 60 mph. at what time will he arrive if he needs to cover 312 miles?

Mr White will arrive at 5:12 pm or 17:12 hrs

Step-by-step explanation:

Let

y ----> the distance in miles

x ----> the time i hours

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

In this problem we have a proportional relationship between the variables x and y

The constant of proportionality k is equal to the speed

so

The linear equation is

At what time will he arrive if he needs to cover 312 miles?

For y=312 miles

substitute in the equation and solve for x

Mr White will arrive at 5:12 pm or 17:12 hrs

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
