inequality word problem

Question

a car travels speeds between 50 and 65 mph. The car travels 4 hours. Write what represents distance.

 

a. 50>d>75

b.d<50 or d>65

c. D>260

d. 200 <= d <=

Answer 1

We know that Distance = Rate x Time

We are given R1 = 50mph, R2 = 65mph, and Time = 4 hours

 

So, at R1, the Distance will be 50mph x 4h = 200miles

At R2, the Distance will be 65mph x 4h = 260miles

 

Therefore, Distance will be equal to or more than 200 miles (=> 200 miles), but less than or equal to 260 miles (<= 260 miles)
