Question

How fast do you need to travel to go 150 km in 3 hours?

• A. 50 km per hour
• B. 20 km per hour
• C. 65 km per hour
• D. 30 km per hour

Answer 1

The correct option is A

50 km per hour

$\because$ Distance = Speed $\times$ Time

$\Rightarrow$ Speed = $\frac{\text{distance}}{\text{time}}$

Given, distance = 150 km and time = 3 hours
$\therefore \text{speed required}=\frac{150}{3}=50$ km per hour
