Higher Order Thinking Lemmy walked 3 1/2 miles on Saturday and miles 4 3/4 on Sunday. Ronnie walked 5 3/8 miles on Saturday. Who
julsineya [31]

Answer:

Lemmy ; 2 7/8 miles

Step-by-step explanation:

Given that :

Distance walked by Lemmy:

Saturday = 3 1/2 miles

Sunday = 4 3/4 miles

Total distance walked by Lemmy:

3 1/2 + 4 3/4

7/2 + 19/4

(14 + 19) / 4

33 / 4

= 8 1/4

Miles walked by Ronnie : 5 3/8

Lemmy walked farther because : 8 1/4 > 5 3/8

Number of distance walked farther than Ronnie :

8 1/4 - 5 3/8

33/4 - 43/8

(66 - 43) / 8

= 23/ 8

= 2 7/8 miles

The distance d (in feet) that it
Marta_Voda [28]

Answer:

40 mph

Step-by-step explanation:

To find the maximum speed at which the car can travel, as the distance it requires to stop is 168 feet, we just need to use the value of d = 168 in the equation, and then find the value of s:

168 = 0.05s^2 + 2.2s

0.05s^2 + 2.2s - 168 = 0

Using Bhaskara's formula: we have:

Delta = 2.2^2 + 4*0.05*168 = 38.44

sqrt(Delta) = 6.2

s1 = (-2.2 + 6.2)/0.1 = 40 mph

s2 = (-2.2 - 6.2)/0.1 = -84 mph (a negative value does not make sense as 's' is the speed of the car)

So the maximum speed of the car is 40 mph
