Awalmart truck driver estimates that it will take him 12 hours to drive 1152 km. after 5 hours, he has driven 520 km. (a) according to his original estimate, how far would he drive in 1 hour? show your number sentence and solution. (b)is he on schedule to arrive on time? use a unit rate to explain your reasoning.

Yes, he will be there on time

Step-by-step explanation:

Based on his original estimate - divide miles by hours

    1152/12 = 96 km/hour

Based on his actual time milage - divide miles by hours

    520/5 = 104 KM/hour

Yes, he is driving faster than he estimated.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
