Question 1 of 12, Step 1 of 1
stellarik [79]

Answer:

325 and 375 mph

Step-by-step explanation:

Given :

Distance between plane A and B = 2800

Recall :

Distance = speed * time

Let speed of A = v1

Speed of B = v2

v1 = v2 + 50

Time taken = 4 hours

Distance = speed * time

Total distance = 2800

2800 = v1 * 4 + v2 * 4

2800 = (4v1) + (4v2)

2800 = 4(v2+50) + 4v2

2800 = 4v2 + 200 + 4v2

2800 = 8v2 + 200

2800 - 200 = 8v2

2600 = 8v2

v2 = 2600/8

v2 = 325 mph

v1 = v2 + 50

v1 = 325 + 50

v1 = 375 mph

a wooden fruit crate will hold 62 pounds of fruit. the crate already has 18 pounds of fruit in it. which inequality represents t
tatuchka [14]

Answer:

p + 18 \leq 62

Step-by-step explanation:

Given

Total = 62\ lb

Current = 18\ lb

Required

Write an inequality to represent the scenario?

Represent the additional number of pounds with p.

When p is added to the current pounds, the weight must be less than or equal to the total possible weights

In other words:

p + current \leq total

Substitute values for current and total

p + 18 \leq 62

Hence, the inequality that describes the scenario is: p + 18 \leq 62
