Answer:

It takes 3 1/3 hours  or 3 hours and 20 minutes

Step-by-step explanation:

We know that distance equals rate time time

D= rt

The distance = 150 miles and the rate is 45 miles per hour

150 =45*t

Divide by 45

150/45 = 45t/45

150/45 =t

10/3

3 1/3 = t

It takes 3 1/3 hours  or 3 hours and 20 minutes

A merchant bought some shirts for $120. The next day the price charged for each shirt was reduced by $1. The merchant calculated
Goshia [24]

Answer:

The merchant buys 30 shirts originally.

Step-by-step explanation:

Let us assume that the merchant bought x numbers of shirts in $120.

So, the cost for each shirt is $\frac{120}{x}.

Now, if the cost for each shirt is reduced by 1$, then he would have bought 10 shirts more i.e. (x + 10) shirts in $120.

So, we can write the following equation as  

(\frac{120}{x} - 1)(x + 10) = 120

⇒(120 - x)(x + 10) = 120x

⇒ 120x - 10x + 1200 - x² = 120x

⇒ x² +10x - 1200 = 0

⇒ x² + 40x - 30x - 1200 = 0

⇒(x + 40)(x - 30) = 0

⇒ x = - 40 or x = 30

But x can not be negative.

Hence, the merchant buys 30 shirts originally. (Answer)
