QuestionExpress each rate in simplest form. a 10 km in 2 hours b $\$ 650$ for 13 hours c 2800 km in 20 days

Studdy Solution
For part (c), simplify the rate of $2800$ km in $20$ days.
Divide both the distance and the time by their greatest common divisor (GCD).
The GCD of $2800$ and $20$ is $20$.
$$\frac{2800 \text{ km}}{20 \text{ days}} = \frac{2800 \div 20 \text{ km}}{20 \div 20 \text{ days}} = \frac{140 \text{ km}}{1 \text{ day}}$$
The simplified rates are: a. $5 \text{ km per hour}$ b. $\$50 \text{ per hour}$ c. $140 \text{ km per day}$
