Two consecutive numbers have a sum of 123. What are the two numbers?

61 and 62

Step-by-step explanation:

Represent 2 consecutive unknown numbers:

x, x + 1

When they are added, the result is 123

Add

x + x + 1 = 123

2x + 1 = 123

Subtract 1 from both sides of the equation

2x = 122

Divide both sides of the equation by 2

x = 61

x + 1 = 62

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to
