Quick. one car traveled 220 miles and drove 10 mph hour slower than a second car which drove 260 miles. if the cars were traveling for the same time, how fast was the first car traveling?

65 mph

75 mph

55 mph

85 mph

55mph

Step-by-step explanation:

car A distance, d1= 220

car b distance, d2= 260

speed of car A, s1= speed of car B- 10

let speed of car B be s2

s1= s2-10

speed = distance/time

time= distance/speed

As time of car A= time of car B

     distance of Car A/speed of Car A=distance of Car B/speed of Car B

220/s2-10= 260/s2

s2=(s2-10)260/220

s2=65

s1= s2- 10

  = 65-10

   =55

hence speed of first car is 55mph !

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
